- DOS calls and EMS/RAM disk, etc.
-
- Your <CONFIG.HP> file contains this entry ... OVERLAY PRAMETER
-
- With the file OVERLAY.COM in the Hyplus directory or at least
- in a directory named by your AUTOEXEC.BAT path statement, the
- following entries after Overlay Parameter are possible:
-
- (blank) DOS, <DOS PONG>, and EDITOR calls work with Hyplus
- remaining in memory.
-
- -e DOS, <DOS PONG>, and EDITOR calls core-dump Hyplus
- to EMS memory, freeing all but 7.5k of memory for
- use by other programs. Upon exit from the called
- application, Hyplus instantly reloads itself.
-
- -dPATH Same as -e excepts call core-dumps Hyplus to a
- named directory (RAM, hard, or floppy disk).
-
- Special notes: All my programs (MAX, HOU, TR, etc) use OVERLAY.COM
- meaning all can shell out to DOS or each other. In addition, my
- core-dump operations are re-entrant meaning it supports chains of
- calls between programs and DOS, with full backstep capability.
