hello guys! um dealing with ancient code which has been coded 10 years ago..some of the parameters were obsolete and yet, dunno how to fix it
..2 b honest, i only learnt c++ but not c, and um just an undergraduate student,having practical training rite now, struggling my way to convert this OS2 base coding, so that it can be run in windows base. i have loaded all the header file needed from the mainframe to my PC,but then, these errors occured..with my limited knowledge of c,can you guys help me out? thanks!

<<end of errors>>
hurm...what seems to be the problem?
the code is quite long,have to admit it's the longest code i've eva deal with..
oh ya, actually the errors came from the header file,so um just gonna post the problematic header file.. ..really need ur help guys! thanks!
