Introduction

SIC (*) is a command line interpretor, written in FORTRAN and callable as a subroutine by any program. It provides a command language rather similar to the VAX-VMS DCL language, with the following major features:

• resolution of command abbreviations
• definition of symbols
• macro capabilities with arguments substitution during execution
• log file
• multi-language structure
• loop buffers for repetitive actions
• variables, arithmetic and logical expressions evaluation
• structured logical tests
• error recovery
• stack buffer
• keypad editing of command lines on VT200 compatible devices
• NEW!: GUI interface on Motif systems

This manual contains several chapters. Chapter 2 (The SIC monitor) should be read by every user before using SIC. Chapter 3 contains a copy of the internal help files of SIC. Chapter 4 is a programming manual for the user who would like to use SIC to create its own application. Chapter 5 is a list of all possible SIC error messages and of their most usual recovery procedures. This reference may be useful if you encounter an error message which you do not understand while running SIC.
