1. You can't write to an .exe under OS/2, because the System opens the file
in a sharing Mode,  When you start a second task with the program, the
System doesn't load the code twice.

2. OS/2 uses Virtual Memory and can swap pages (4096byte in size) out of
memory or back. But the Code of a program is only discarded and if the
System uses the code again, it reloads it from the .EXE. Code isn't swapped
out to the SWAPPER.DAT 

3. The Code-Segment of a program ist ReadOnly and so you can get problems
with statement 2.

4. What about using the program in a Network, when every user wants to save
the configuration ?

5. It's not a good programming practice.

6. You should use the PRFxxxx Functions to write to an .INI File. Best way
to do is to create you own and not to write to OS2.INI or OS2SYS.ini,
because of better copyying the configuration-data to a different machine.
