"Lars Hansen" <lars.o.hansen gmx.de> writes:

the following program compiled with sc "sourcefilename" produces a program
which does the following:

appends b at end of file, places b at file offset 138

it should place b at file offset 71 and 138  (b is the char array)

(also compiling with -o or -mtd produces this wrong code)

Also two qs:
1. when compiled with -mt there's the optlink warning 23 "No Stack": so does
the compiler not generate pushes or will they result in code loss?
2. when compiling with -mtd x.n filenames are shortened to x.3 filenames
(x<8)resulting in the file rt.htm created by the program. Is there a
workaround?

small correction: -mt causes filename truncation, not -mtd
