| 21 | * Update 2006-01-23 More fixes, in call to mktemp and in 2501 support, also thanks\r |
| 22 | to Carl Claunch.\r |
| 23 | \r |
| 24 | * Update 2006-01-03 Fixed bug found by Carl Claunch: feed function does not\r |
| 25 | cause an operation complete interrupt. Standard DMS routines were not\r |
| 26 | sensitive to this but DUP uses its own interrupt handler, and this\r |
| 27 | is why DUP would hang at end of deck.\r |
| 28 | \r |
| 29 | * Update 2005-05-19 Added support for 2501 reader\r |
| 30 | \r |
| 31 | * Update 2004-11-08 Merged in correct physical card reader code\r |
| 32 | \r |
| 33 | * Update 2004-11-02: Added -s to boot command: don't touch console switches.\r |
| 34 | \r |
| 35 | * Update 2004-06-05: Removed "feedcycle" from cr_reset. Reset should not touch the card reader.\r |
| 36 | \r |
| 37 | * Update 2004-04-12: Changed ascii field of CPCODE to unsigned char, caught a couple\r |
| 38 | other potential problems with signed characters used as subscript indexes.\r |
| 39 | \r |
| 40 | * Update 2003-11-25: Physical card reader support working, may not be perfect.\r |
| 41 | Changed magic filename for stdin to "(stdin)".\r |
| 42 | \r |
| 43 | * Update 2003-07-23: Added autodetect for card decks (029 vs binary),\r |
| 44 | made this the default.\r |
| 45 | \r |
| 46 | * Update 2003-06-21: Fixed bug in XIO_SENSE: op_complete and response\r |
| 47 | bits were being cleared before the DSW was saved in ACC. Somehow DMS\r |
| 48 | worked with this, but APL didn't.\r |
| 49 | \r |
| 50 | * Update 2002-02-29: Added deck-list option.\r |
| 51 | \r |
| 52 | * Update 2003-02-08: Fixed error in declaration of array list_save, pointed\r |
| 53 | out by Ray Comas.\r |

| 56 | * USAGE NOTES\r |
| 57 | * -----------------------------------------------------------------------\r |
| 58 | \r |
| 59 | * Attach switches:\r |
| 60 | \r |
| 61 | The ATTACH CR command accepts several command-line switches\r |
| 62 | \r |
| 63 | -q quiet mode, the simulator will not print the name of each file it opens\r |
| 64 | while processing deck files (which are discussed below). For example,\r |
| 65 | \r |
| 66 | ATTACH -q @deckfile\r |
| 67 | \r |
| 68 | -l makes the simulator convert lower case letters in text decks\r |
| 69 | to the IBM lower-case Hollerith character codes. Normally, the simulator\r |
| 70 | converts lower case input to the uppercase Hollerith character codes.\r |
| 71 | (Lowercase codes are used in APL\1130 save decks).\r |
| 72 | \r |
| 73 | -d prints a lot of simulator debugging information\r |
| 74 | \r |
| 75 | -f converts tabs in an ascii file to spaces according to Fortran column conventions\r |
| 76 | -a converts tabs in an ascii file to spaces according to 1130 Assembler column conventions\r |
| 77 | -t converts tabs in an ascii file to spaces, with tab settings every 8 columns\r |
| 78 | (See below for a discussion of tab formatting)\r |
| 79 | \r |
| 80 | -p means that filename is a COM port connected to a physical card reader using\r |
| 81 | the CARDREAD interface (see http://ibm1130.org/sim/downloads)\r |
| 82 | \r |
| 83 | The ATTACH CP command accepts the -d switch.\r |
| 84 | \r |
| 85 | * Deck lists\r |
| 86 | If you issue an attach command and specify the filename as\r |
| 87 | "@filename", the file is interpreted as a list of filenames to\r |
| 88 | be read in sequence; the effect is that the reader sees the concatenation\r |
| 89 | of all of the files listed. The simulator "reset" does NOT rewind the deck list.\r |
| 90 | \r |
| 91 | Filenames may be quoted if they contain spaces.\r |
| 92 | \r |
| 93 | The strings %1, %2, etc, if they appear, are replaced with arguments passed\r |
| 94 | on the attach command line after the name of the deckfile. These can be the\r |
| 95 | arguments to ibm1130, or to the "do" command if a "do" script is executing, if the\r |
| 96 | attach command is constructed this way:\r |
| 97 | \r |
| 98 | attach @deckfile %1 %2 %3\r |
| 99 | \r |
| 100 | This will pass the ibm1130 or do script arguments to attach, which will make\r |
| 101 | them available in the deckfile. Then, for instance the line\r |
| 102 | \r |
| 103 | %1.for\r |
| 104 | \r |
| 105 | would be substituted accordingly.\r |
| 106 | \r |
| 107 | Blank lines and lines starting with ; # or * are ignored as comments.\r |
| 108 | \r |
| 109 | Filenames may be followed by whitespace and one or more mode options:\r |
| 110 | The mode options are:\r |
| 111 | \r |
| 112 | b forces interpration as raw binary\r |
| 113 | a forces conversion from ascii to 029 coding, tabs are left alone\r |
| 114 | af forces 029 ascii conversion, and interprets tabs in Fortran mode\r |
| 115 | aa forces 029 ascii conversion, and interprets tabs in 1130 Assembler mode\r |
| 116 | at forces 029 ascii conversion, and interprets tabs with settings every 8 spaces\r |
| 117 | \r |
| 118 | If "a" or "b" mode is not specified, the device mode setting is used. In this case,\r |
| 119 | if the mode is "auto", the simulator will select binary or 029 by inspecting each\r |
| 120 | file in turn.\r |
| 121 | \r |
| 122 | If a tab mode is not specified, tabs are left unmolested (and are treated as invalid characters)\r |
| 123 | \r |
| 124 | Example:\r |
| 125 | \r |
| 126 | attach cr @decklist\r |
| 127 | \r |
| 128 | reads filenames from file "decklist," which might contain:\r |
| 129 | \r |
| 130 | file01.for xf\r |
| 131 | file02.dat a\r |
| 132 | file03 bin b\r |
| 133 | file04 bin\r |
| 134 | \r |
| 135 | ('a' means 029, so, if you need 026 coding, specify the\r |
| 136 | device default as the correct 026 code and omit the 'a' on the text files lines).\r |
| 137 | \r |
| 138 | Literal text cards can be entered in deck files by preceding an input\r |
| 139 | line with an exclamation point. For example,\r |
| 140 | \r |
| 141 | !// JOB\r |
| 142 | !// FOR\r |
| 143 | program.for\r |
| 144 | !// XEQ\r |
| 145 | program.dat\r |
| 146 | \r |
| 147 | looks like two literal supervisor control cards, followed by the contents\r |
| 148 | of file program.for, followed by an // XEQ card, followed by the contents\r |
| 149 | of file program.dat.\r |
| 150 | \r |
| 151 | %n tokens are not replaced in literal cards.\r |
| 152 | \r |
| 153 | The line\r |
| 154 | \r |
| 155 | !BREAK\r |
| 156 | \r |
| 157 | has a special meaning: when read from a deck file, it stops the\r |
| 158 | emulator as if "IMMEDIATE STOP" was pressed. This returns control to\r |
| 159 | the command interpreter or to the current DO command script.\r |
| 160 | \r |
| 161 | * Card image format.\r |
| 162 | Card files can be ascii text or binary. There are several ASCII modes:\r |
| 163 | CODE_029, CODE_26F, etc, corresponding to different code sets.\r |
| 164 | Punch and reader modes can be set independently using\r |
| 165 | \r |
| 166 | set cr binary set cp binary *\r |
| 167 | set cr 029 set cp 029\r |
| 168 | set cr 026f set cp 026f\r |
| 169 | set cr 026c set cp 026c\r |
| 170 | set cr auto *\r |
| 171 | \r |
| 172 | (* = default mode)\r |
| 173 | \r |
| 174 | In "auto" mode, the card reader will examine the first 160 bytes of\r |
| 175 | the deck and guess whether the card is binary or 029 text encoded.\r |
| 176 | When a deck file is used with auto mode, the simulator guesses for\r |
| 177 | each file named in the deck file.\r |
| 178 | \r |
| 179 | * Tab formatting. The attach command and deckfile entries can indicate\r |
| 180 | that tabs are to be converted to spaces, to help let you write free-form\r |
| 181 | source files. There are three tab conversion modes, which are set\r |
| 182 | with the attach command or in a decklist, as discussed earlier\r |
| 183 | \r |
| 184 | Fortran mode:\r |
| 185 | Input lines of the form\r |
| 186 | \r |
| 187 | [label]<tab>statement\r |
| 188 | \r |
| 189 | or\r |
| 190 | \r |
| 191 | [label]<tab>+continuation\r |
| 192 | \r |
| 193 | (where + is any nonalphabetic character) are rearranged in the\r |
| 194 | appropriate manner:\r |
| 195 | \r |
| 196 | 1 2\r |
| 197 | 12345678901234567890...\r |
| 198 | ------------------------\r |
| 199 | label statement\r |
| 200 | label+continuation\r |
| 201 | \r |
| 202 | However, you must take care that you don't end up with statement text after column 72.\r |
| 203 | \r |
| 204 | Input lines with * or C in column 1 (comments and directives) and lines without tabs\r |
| 205 | are left alone.\r |
| 206 | \r |
| 207 | (The ! escape is not used before Fortran directives as before Assembler directives)\r |
| 208 | \r |
| 209 | Assembler mode:\r |
| 210 | Input lines of the form\r |
| 211 | \r |
| 212 | [label]<whitespace>[opcode]<tab>[tag][L]<tab>[argument]\r |
| 213 | \r |
| 214 | are rearranged so that the input fields are placed in the appropriate columns\r |
| 215 | \r |
| 216 | The label must start on the first character of the line. If there is no label, \r |
| 217 | the first character(s) before the opcode must be whitespace. Following the opcode, there\r |
| 218 | MUST be a tab character, followed by the format and tag. Following the format and tag \r |
| 219 | may be exactly one whitespace character, and then starts the argument.\r |
| 220 | \r |
| 221 | Input lines with * in column 1 and blank lines are turned into Assembler comments,\r |
| 222 | with the * in the Opcode field.\r |
| 223 | \r |
| 224 | Assembler directive lines at the beginning of the deck must be preceded by\r |
| 225 | ! to indicate that they are not comments. For example,\r |
| 226 | \r |
| 227 | !*LIST\r |
| 228 | * This is a comment\r |
| 229 | \r |
| 230 | Plain Tab mode:\r |
| 231 | Tabs are replaced with spaces. Tab settings are assumed to be eight characters wide,\r |
| 232 | as is standard for vi, notepad, etc.\r |
| 233 | \r |
| 234 | * CGI mode note: The command\r |
| 235 | \r |
| 236 | attach cr (stdin)\r |
| 237 | \r |
| 238 | will attach the card reader to stdin. However, this is not compatible\r |
| 239 | with the default encoding autodetect feature, so the command must be\r |
| 240 | preceded with\r |
| 241 | \r |
| 242 | set cr 029\r |
| 243 | \r |
| 244 | * -----------------------------------------------------------------------\r |
| 245 | * PROGRAMMING NOTES\r |
| 246 | * -----------------------------------------------------------------------\r |
| 247 | \r |
| 248 | NOTE - there is a problem with this code. The Device Status Word (DSW) is\r |
| 249 | computed from current conditions when requested by an XIO load status\r |
| 250 | command; the value of DSW available to the simulator's examine & save\r |
| 251 | commands may NOT be accurate. This should probably be fixed. (I think there's\r |
| 252 | a way to have the expression evaluator call a routine? That would be one\r |
| 253 | way to solve the problem, the other is to keep DSW up-to-date all the time).\r |
| 254 | \r |
| 255 | The 1442 card read/punch has several cycles:\r |
| 256 | \r |
| 257 | feed cycle: moves card from hopper to read station\r |
| 258 | card from read station to punch station\r |
| 259 | card from punch station to stacker\r |
| 260 | \r |
| 261 | read or punch: operates on card at read or punch station (but not both).\r |
| 262 | \r |
| 263 | The simulator requires input cards to be read from the file attached\r |
| 264 | to the card reader unit. A feed cycle reads one line (text mode) or\r |
| 265 | 160 bytes (binary mode) from the input file to the read station buffer,\r |
| 266 | copies the read station buffer to the punch station buffer, and if\r |
| 267 | the punch unit is attached to a file, writes the punch station buffer to\r |
| 268 | the output file.\r |
| 269 | \r |
| 270 | The read and punch cycles operate on the appropriate card buffer.\r |
| 271 | \r |
| 272 | Detaching the card punch flushes the punch station buffer if necessary.\r |
| 273 | \r |
| 274 | As does the 1442, a read or punch cycle w/o a feed cycle causes a\r |
| 275 | feed cycle first.\r |
| 276 | \r |
| 277 | A feed cycle on an empty deck (reader unattaced or at EOF) clears\r |
| 278 | the appropriate buffer, so you can punch w/o attaching a deck to\r |
| 279 | the card reader.\r |
| 280 | \r |
| 281 | (Note: Carl Claunch determined by examining DUP code that a feed cycle\r |
| 282 | does not cause an operation complete interrupt).\r |
| 283 | \r |
| 284 | -- -- this may need changing depending on how things work in hardware. TBD.\r |
| 285 | || A read cycle on an empty deck causes an error.\r |
| 286 | || Hmmm -- what takes the place of the Start button on\r |
| 287 | -- the card reader?\r |
| 288 | \r |
| 289 | Binary format is stored using fxwrite of short ints, in this format:\r |
| 290 | \r |
| 291 | 1 1\r |
| 292 | 2 2 0 1 2 3 4 5 6 7 8 9\r |
| 293 | * * * * * * * * * * * * 0 0 0 0\r |
| 294 | \r |
| 295 | MSB LSB\r |
| 296 | byte 0 [ 6] [ 7] [ 8] [ 9] 0 0 0 0\r |
| 297 | byte 1 [12] [11] [ 0] [ 1] [ 2] [ 3] [ 4] [ 5] \r |
| 298 | \r |
| 299 | This means we can read words (little endian) and get this in memory:\r |
| 300 | \r |
| 301 | 12 11 0 1 2 3 4 5 6 7 8 9 - - - -\r |
| 302 | \r |
| 303 | which is what the 1130 sees.\r |
| 304 | \r |
| 305 | ASCII can be read in blocks of 80 characters but can be terminated by newline prematurely.\r |
| 306 | \r |
| 307 | Booting: card reader IPL loads 80 columns (1 card) into memory starting\r |
| 308 | at location 0 in a split fashion:\r |
