The format is a soubroutine to do the checking, and a small main() to test it with. It works correctly for all of my credit cards, no other claims of accuracy are made. The code should work on must C compilers, but I've only recently tested it with gcc of Linux. HISTORY The original program was written in BASIC and posted to alt.sources.wanted in October 1994. The original author was Chris Stone . It was then translated into C by Peter Miller and posted to alt.sources later the same month. This program then received more email feedback in the first week the the author's more serious efforts did in the same time. AUTHORS Derived from code by Chris Stone , The High Mountain Software Internet Gateway. Translated to C by Peter Miller, 1994-Oct-28. BUILDING The package is built in the usual way for open source software. Unpack the tarball, and then ./configure to configure the software for your system, and then make to build the software. Then make sure to test the software. Then make install to install the software. readme(ccard)
