Has anyone used the "_Turbo C Memory-Resident Utilities, Screen I/O,
and Programming Techniques_" by Al Stevens to create a memory resident
program?
I inherited a memory resident program that I must maintain. The
program is based on the examples in the book. I have compiled and run
the program successfully on '286 and '386 machines, but I cannot get
the program to run on 8088 machines. When I press the program's "hot
key", the PC "locks up". Sometimes a warm boot will revive the
machine, other times a cold boot is required.
I have looked everywhere that I know of to make sure that the
compiler/linker are not generating machine specific instructions. As
far as I can tell, the program is being loaded into memory properly.
One thing that I cannot do the way the book suggests, is assembling
c0.asm. The book uses the commands:
C>masm c0,c0t /ML /D__TINY__;
C>masm c0,c0s /ML /D__SMALL__;
When I run masm for the small module, the following is displayed:
Microsoft (R) Macro Assembler Version 4.00

c0.ASM(315) : error 9: Symbol not defined NullCheck
43724 Bytes symbol space free
0 Warning Errors
3 Severe Errors
The Turbo C supplied commands to rebuild c0t and c0s tell you to use
the /MX option, not the /ML option. If /MX is used, there are no
error messages displayed. In either case, the memory resident program
does not work properly.
Any suggestions would be greatly appreciated.
