Script Processor

From CRYSTALS

Scripts is a macro language for automating tasks in CRYSTALS. It can also be used to write new dialog boxes to appear in the GUI. There are plenty of example scripts (possibly too many) in the /script/ subdirectory of your CRYSTALS installation.

Each script has a filename ending in .scp (e.g. xfour.scp) and is invoked from the CRYSTALS command line by typing, for example,

#script xfour
