tests/130-expr.R

In redcas: An Interface to the Computer Algebra System 'REDUCE'

## $Id: 130-expr.R,v 1.2 2024/10/19 13:40:08 mg Exp $

## Purpose: Execute 130-expr.red for both CSL and PSL and compare results to expected

## $Log: 130-expr.R,v $
## Revision 1.2  2024/10/19 13:40:08  mg
## 1. added --nogui option for csl
## 2. added aelen function to compare lengths of expect and actual and their elements

## Revision 1.1  2024/09/04 11:27:35  mg
## initial version
