Re: A86: Hiding Programs
If the first character of a program is less than 'A',
then it is not detected by any shells or the os. To
hide a program like this, use this routine (it isn't
tested):
ld hl,progname-1
rst 20h
rst 10h
ld de,6
add hl,de ;point hl to first character in VAT
ld (hl),0
progname:
.db 4,"prog" ;length followed by name
This routine changes the program's name to:
.db 0,"rog"
