Hi, it's me again.  Umm... first thing's first. You need to define prototypes
for the functions you want to call similar to this:

pascal int function(int a,float b,char *c);

Note the 'pascal' qualifier.
Also, you may or may not have to define the Pascal routines in question
inside a unit.  If the routines are Pascal library routines, then no
unit is required (Link will search the paslib).

BTW, what version of C do you have? I use file operations all the time and
have no problems.  You said you open a file, and it goes to the end.
Exactly what statements are you using to open the file (send me source code).

Also- why didn't you leave the program in pascal?
Also- did you say you have a pascal->C conversion program, or just a
      method?
