Hello troubleshooter,

I have just started to port an old 16bit code to DJGPP'c gcc compiler.
I have a small segment of code which I can not port. I ueses SREGS
structure.

Here is an example. If someone can look at it and let me know how to
translate into DJGPP's. I have been reading FAQ section 17.6 and 18.2
and more. BUT I am still not being able to solve the mystery of
register.

My problem area is:
FP_SEG and FP_OFF(). DJGPP does not have these two functions.
Can I write my own? OR Can I somehow translate them into DJGPP.

Will appreciate all the help

Sincerely,

Altaf
