These instructions will direct you how to change Manage Your Money
Version 1.5 so that it will run on your hard disk without requiring
a system disk in your floppy drive. Naturally these changes are
meant to be used by licensed users only.
This file represents several hours of stepping through compiled basic
(yechhh a fate worse than death) in order to remove the offending code.

Run setup first to set up MYM for your system. Then run all three disks
onto your hard disk. Then use Debug as instructed on MYM.exe. From then
on you can run MYM directly from your hard disk with no system disk.
You can also use backup or copy to save MYM and its files to a floppy
disk. This allows you to make extra backups etc. You must remember that
you have to use setup.exe on the original system disk to change the system
setup as to number or drives, where to look for data files, screen type etc.
This was tested on DOS 3.0 using debug 3.0 for earlier versions of DOS and
debug you might have to look up or down in memory one or two sectors to find
the proper locations.
At location 04F0 you will find CALL 44F2 or byte string E8,FF,3F.
Change these three bytes to NOP NOP NOP or byte string 90,90,90.
This removes the call to the floppy disk.
At location 72DE you will find CALL 4848 or byte string E8,67,D5
Change these three bytes to NOP NOP NOP or byte string 90,90,90.
This removes those nasty little checks for the system disk.
Make sure to operate on a backup file and not the original. I suggest
you set up MYM for your system first from the original disks and then
run them on your hard disk. Then make a copy of MYM.EXE and use that
to operate on. When you have it working copy it back to your hard disk
and you're in business.
ANDREW TOBIAS if you should read this: With a good financial statement,
some assembly language routines to gain speed, a return to DOS after exit
instead of rebooting, and other minor polishes you will have a darn good
piece of software which will be really useful to almost anybody with a
computer and even a small business or shop.
