Description

This program provides a Mathematica function called FormGet which reads output files from FORM into Mathematica. (FORM is a computer algebra system commonly used in high energy physics.)

The output format of FORM is slightly different from Mathematica's InputForm, and while the translations (e.g. round brackets into square brackets for functions) are in most cases straightforward to perform with any decent pattern-matching language like perl or awk, it becomes a pain in the neck to program this for every FORM file one may want to read.

In addition, FormGet preserves the structure of the FORM output if it was grouped into common factors with the bracket command.

For instructions on compiling and usage, see the comments at the beginning of FormGet.tm.
