February 15, 2003 wrong code generated by tiny program of below thread | ||||
---|---|---|---|---|
| ||||
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?
dmc version 8.29n
