PATH_SEP

The PATH_SEP function returns the proper file path segment separator character for the current operating system. This is the character used by the host operating system for delimiting subdirectory names in a path specification. Use this function instead of hard-coding separators to make code more portable.

This routine used to be written in the IDL language, but was rewritten in the C programming language for IDL 7.1.
