Introduction

This chapter explains how to call a main program in one language from a main program in another. Additional interlanguage communication information can be found in the SAS/C Compiler Interlanguage Communication Feature User's Guide. This publication describes how to write more complicated multilanguage applications, such as a COBOL main program that calls C subroutines.

Using the indep Option for Interlanguage Communication contains information on C functions calling or being called by other languages without the use of the interlanguage communication (ILC) feature. Use of the ILC feature is highly recommended for new programs. Using the indep Option for Interlanguage Communication explains the techniques that were required before this feature was available.
