/ IPL GENERATING PROGRAM / LAST EDIT: 08-OCT-1991 12:00:00 CJL / MUST BE ASSEMBLED WITH '/F' SWITCH SET. / THIS IS A UTILITY NAMED IPLGEN (AKA K12IPG) TO CREATE FIELD0.IPL (AKA / K12FL0.IPL) AND FIELD1.IPL (AKA K12FL1.IPL). THESE FILES ARE IN TURN MEANT / FOR USE WITH THE DIRECT LOADING PROGRAM IPLOAD (AKA K12IPL). FUTURE VERSIONS / OF K12MIT.SV MAY "GROW" TO USE FIELD TWO, IN WHICH CASE THIS PROGRAM WILL HAVE / TO BE CHANGED. / THIS PROGRAM ALWAYS RESIDES IN THE NEXT FIELD BEYOND K12MIT.SV, AND CREATES / FILES FOR ALL FIELDS LOWER THAN ITS LOADING FIELD. THIS CURRENTLY REQUIRES A / 12K MACHINE TO ENCODE ALL LOCATIONS 00000-07577 AND 10000-17577. / USAGE: / SINCE K12MIT.SV IS A COMPLETE IMAGE FILE, IT MUST BE LOADED FIRST IN IMAGE / MODE, AND THEN OVERLAYED WITH THE BINARY OF THIS ASSEMBLY: / .PAL IPLGEN<IPLGEN/E/F ASSEMBLE IPLGEN PROGRAM. / .LOAD K12MIT.SV/I$*IPLGEN/G=20200 LOAD K12MIT.SV IN IMAGE MODE; THE $ / INDICATES USING <ESC> TO TERMINATE / THE LINE; THEN LOAD IPLGEN AND START. / THE FILES SYS:FIELD0.IP AND SYS:FIELD1.IP WILL BE CREATED AND THE PROGRAM / EXITS TO THE KEYBOARD MONITOR. THE RESULTANT FILES MAY BE EDITED AS LONG AS / THE RULES OF .IPL FORMAT ENCODING ARE OBEYED (ADDITIONAL LOWER-CASE LEADER / COMMENTS SHOULD BE ADDED AT THE BEGINNING, AND UNRESTRICTED COMMENTS AT THE / END). / ERROR MESSAGES: / ERROR NUMBER PROBABLE CAUSE / 5 ERROR WHILE ATTEMPTING TO ENTER OUTPUT FILE. / 6 OUTPUT FILE LARGER THAN AVAILABLE FILE SPACE. / 7 ERROR WHILE CLOSING THE OUTPUT FILE. / 8 I/O ERROR WHILE ENCODING FILE DATA. / EQUATED SYMBOLS.
