	Big differance there. Informix 4gl doesn't generate big modules 
either: I just compiled a 200 lines program and got a 30K object module.
The same program though when linked with the libraries, produced a 300K 
executable.

The code that's generated is bigger than the original source because there
are a lot of automatic error checking, and conversions that are done
for you (after all that's what's so nice about 4gls.), but this increase is not
that significant. The main reason your program grows so much is because 
the linker links in the display and menu libraries which includes a lot 
of stuff. Than again how often are you going to be using I4gl to write
a 4 lines menu ?

The original poster though was asking about linking C programs to 4gls. This
he can do without looking at the C code by just mixing in 4gl files,
C files, and object files generated by other compilers all on the command line:
c4gl file1.4gl file2.c file3.o .... -o prog
