Could anyone help me on Calling a C programme from PROIV.

Thanx.

For clarification: Is it a self-contained C program you want to call (ie. a separate executable) or do you want to call C functions (ie. individual subroutines, for example in a library). There's a big difference

Siddharth,

There are a couple of commands that you can use:

In 4.6
#stat = SYSTEM('c program')

In 5.5
CLIENT.EXECUTE('program to run c program', 'c program')

hth,

Joseph

Hi Richard,
I want input on both i.e. separate executable C program as well as individual subrutines.

Siddharth,

Joseph has covered how to call a separate program.
To call C functions you need to use the LINK() statement in logic and to have linked your C code into the ProIV kernel.
See the sections entitled "Procedural Language Interface" in the ProIV Environment Guide.
There is quite a steep learning curve involved with calling C functions from ProIV if you are not already a reasonably experienced C programmer.
