Typically a shell is the first to add environment variables but it could just as easily be any language that calls the C environment variable APIs (e.g. Python and JAVA). There is an open source version of the STDLIB (Standard library) called GLIBC located at https://sourceware.org/git/?p=glibc.git;a=tree;f=stdlib;h=4c362998447b7664b4268fa732e90389bc1b8410;hb=HEAD which implements GETENV, PUTENV and other related functions. IBM most likely did a similar implementation in IBM C but without seeing the source, I can't be 100% sure. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
