[comp.os.msdos.programmer] DOS version question

hogue@hsi86.hsi.com (Jim Hogue) (05/01/91)

When I run a program (compiled with zortech c++ v2.1 under DOS v3.3) on
v2.1 of DOS, opens work and fopens fail.  Is this expected?  Am I
asking to much to be able to run programs compiled under 3.3 to run
under 2.1?  Do I need to poke something just right to make fopen issue
the correct open?  Is this a Zortech only problem and I should get
another (supposedly better :-) compiler?  Or is this just another case of
RTFM :-)?  As always any help will be appreciated.  Thanks.
