+/ VER 1.0 1.NOV. 1980 H.A.\r
+/ VER 2.0 12.NOV 1980 H.A.\r
+/ VER 2.1 20.NOV 1980 H.A. CORRECTS BUG IN SYMBOL CONCERNING #XFCTX,#XFCTY\r
+/ VER 3.0 27.NOV 1980 H.A. INSERTS SYMBOL (999.,999.,....)\r
+/ VER 3.1 27.NOV.1980 H.A. CORRECTS PEN UP/DOWN TIMING ERROR\r
+/ VER 3.2 18.JAN.1981 H.A. CORRECTS WHERE AND OVERLAY PROBLEMS\r
+/ VER 3.3 4.AUG.1982 H.A. REDUCES NUMBER OF EXTERNAL REFERENCES\r
+/\r
+/ UPDATES:\r
+/ 1. PLEXIT LOCKED OUT THE PLOTTER.\r
+/ 2. PLOTS DIDN'T DROVE PLOTTER TO THE ORIGIN\r
+/ * #XONCE IS REMOVED, SO #XNTST IS CALLED FROM PLOTS ALL TIMES\r
+/ 1-NOV-80 H.A.\r
+/ 3. FACTOR DID NOT WORK CORRECT ALL THE TIMES.\r
+/ FACTOR(1),XYPLOT(1,1),FACTOR(2),XYPLOT(1,1) DID NOT WORK\r
+/ 4. TRUNCATION ERROR IN XYPLOT CAUSED ROUNDING PROBLEMS:\r
+/ XSTEPS=INT(INT(X/#XINCR)*FACTOR)\r
+/ * FACTOR NOW WORKS CORRECT IN ANY CASE\r
+/ * FACTOR NOW HAS AN OPTIONAL SECOND PARAMETER. IF BOTH PRESENT\r
+/ * THEY SPECIFY THE X-FACTOR AND THE Y-FACTOR.\r
+/ * A NEGATIVE FACTOR IS NO MORE VALID YET. (ERROR WALKBACK)\r
+/ * ZERO FACTOR DISABLES PLOTTING.\r
+/ * XYPLOT NOW COMPUTES XSTEPS=INT(X/#XINCR*FACTOR)\r
+/ * WHERE HAS GOT AN OPTIONAL FOURTH PARAMETER FOR THE Y-FACTOR.\r
+/ * IF X AND Y FACTOR DO NOT MATCH AND THERE ARE ONLY THREE PARAMETERS\r
+/ * AN ERROR WALKBACK IS TAKEN.\r
+/ 7-NOV-80 H.A.\r
+/ 5. SYMBOL CALLS #XMBTB TO LOAD THE SYMBOL TABLE\r
+/ 12-NOV-80 H.A.\r
+/ 6. CALLING SYMBOL/NUMBER WITH X/Y EQUAL TO 999. WILL REPLACE THE\r
+/ 999. WITH THE ACTUAL POSITION OF THE PEN. VERY USEFULL IF YOU\r
+/ ARE EDITING AN OUTPUT LINE USEING SOME CALLS TO SYMBOL & NUMBER.\r
+/ IF YOU CALL FACTOR PRIOR TO SYMBOL(999.,....) THEN THE POSITION\r
+/ OF THE PEN IS NEVER CHANGED PRIOR PLOTTING THE SYMBOL. BUT THE\r
+/ FACTOR IS USED WHEN PLOTTING THE SYMBOL.\r
+/ 27-NOV-80 H.A.\r
+/ 7. EACH TIME XYPLOT WAS CALLED IT ISSUED A PEN UP/DOWN COMMAND.\r
+/ THIS CAUSED A STEP BY STEP MOVING OF THE PEN ALTHOUGH THE\r
+/ DIRECTION WAS NOT CHANGED. INTERFACE PROBLEM.\r
+/ NOW WE ISSUE THE PEN MOVE COMMAND ONLY WHEN WE WANT TO CHANGE\r
+/ THE DIRECTION OF THE PEN. THIS SPEEDS UP THE PLOTTER!\r
+/ * NOT VALID PEN VALUES (NOT -3 TO 3) CAUSE #ARGERR WITH X0 =1\r
+/ 27-NOV-80 H.A. A HARD DAY'S NIGHT.... AND MIDNIGHT TOO!\r
+/ 8. REMOVES BUG IN WHERE ROUTINE\r
+/ 9. TOO LARGE DELTA X (DELETA Y) CAUSE #ARGER WITH X0=2 (3)\r
