All files containing C code must be named with the `` .c'' suffix.
Loading functions from more than one C file can be done by issuing commands at the IC prompt to load each of the files. For example, to load the C files named foo.c and bar.c:
C> load foo.c
C> load bar.c
Alternatively, the files could be loaded with a single command:
C> load foo.c bar.c
If the files to be loaded contain dependencies (for example, if one file has a function that references a variable or function defined in the other file), then the second method (multiple file names to one load command) or the following approach must be used.
