- * N Z C P R 203- Z80-Based Command Processor Replacement, Version 2.03 *
- .
- 16c 24427
- * *
- * This is DIF file Mod 0.3 to be combined with mod 0.1 VERS of ZCPR2. *
- * To obtain the full file do: *
- * SSED ZCPR2.ASM <NZCPR203.DIF >NZCPR203.ASM *
- * *
- * 18 FEB 1983 = VERS 2.02 ; BY PETER PINCHIS, TORONTO, ONT. *
- * - DIR routine has been changed to provide user select- *
- * able number of columns for DIR and ERA display. *
- * DIR and ERA shall now page at each full screen. *
- * - CONOUT routine modified to ignore Form feeds. *
- * - ERAV has a new meaning : when FALSE the user is always*
- * prompted except when ERDFLG is present in the command *
- * line. *
- * - The module ZCPRHDR.LIB has been changed and renamed *
- * NZCPRHDR.LIB. *
- * Only this module shall be used to compile NZCPR202 *
- * *
- * 23 FEB 1983 = VERS 2.03 ; BY PETER PINCHIS, TORONTO, ONT. *
- * - Major bug fixed: in the original ZCPR2 mod 0.1 every *
- * time when a wrong command is issued in the multiple *
- * command line ( i.e : a file not found or a wild card *
- * in the save or ren cmd ) ,the ZCPR stops and the rest *
- * of the command line is ignored. *
- * Example: B1>type xxxxx.xxx;pip a:=b:yy.zz;dir *
- * B1>; xxxxx.xxx not found..... *
- * B1>XXXXX.XXX;PIP A:=B:YY.ZZ;DIR? *
- * B1> *
- * The present fix solves this problem : in the above *
- * example the execution continues with PIP and DIR... *
- * However there is a trade-off : IF THE USER OR THE *
- * DRIVE IS NOT WITHIN THE RANGE the execution is *
- * aborted without any prompt. *
- * Use module NZCPRHDR.LIB ver 2.02 to compile this file.*
