Introduction This file describes the installation of the graphics command language DISGCL which is an interpreter based on the graphics software DISLIN. All DISLIN statements can be written to a script file and then be executed with DISGCL, or can be en- tered in an interactive mode. Similar to programming languages such as Fortran and C, high- level language elements can be used within DISGCL. These are variables, operators, expressions, array operations, loops, if and switch statements, user-defined subroutines and func- tions, and file I/O routines. An easy to use interface for data input is given to include data into DISGCL jobs. The format of data files is very simple and useful for most DISLIN plotting routines. Several quickplots are offered by DISGCL which are collecti- ons of DISLIN statements to display data with one command. 2.) Installation of DISGCL The Windows version of DISGCL is distributed as a .zip file created with the file packaging utility ZIP (version 1.9). The .zip file has the file name GCL_nn_W.ZIP where nn is the current version number of DISGCL. To install DISGCL, make the following steps: a) Create a temporary directory and copy all files from the distribution disk to the directory: for example: md c:\temp cd c:\temp copy a:\*.* *.* b) Extract GCL files with the command: unzip -o GCL_11_W c) Run the SETUP program with the command setup - Choose OK - Give the Installation Directory where DISGCL should be in- stalled. The default directory is C:\DISLIN. d) Reconfigure the system Set the DISLIN environment variable to c:\dislin and include c:\dislin\win in your path. If you have installed DISLIN in a different directory, you have to use that directory for the environment variables above. Environment variables can be set or modified with the Control Panel (see Control Panel -> System -> Advanced -> Environment Variables).
