The program DISGCL is an interpreter based on the data plotting library DISLIN. DISLIN statements can be written to a script file after which become executed with DISGCL, or can be entered in an interactive mode. Similar to programming languages, high-level language elements are available in DISGCL such as variables, operators, expressions, array procedures, loops, if and switch statements, user-defined functions and I/O routines.
DISGCL can display graphic information on graphic terminals or store them in metafiles. The supported display types are VGA, X11 and Windows API. The supported file types are GKSLIN, CGM, HPGL, PostScript, PDF, WMF, PNG and TIFF. DISGCL consists of the following features:
-- 9 software fonts where each font provides 6 alphabets.
