VCEXTRACT is a simple program that can be used to read a .vcham file created by VCHFIT and output the non-zero parameters in a format that can be used directly in a VCHFIT input file. The program is command line driven and requires the specification of a small number of arguments.

To run the program type
vcextractXX arg1 arg2 ... file
where XX is the version number, e.g. vcextract100 for package version 10.0, and where arg1 arg2 ... are the arguments, and file is the name of the .vcham file.

By way of example, typing

vcextract100 -o file.out file.vcham

would result in the parameters being read from the file file.vcham and written to the file file.out.
