previously, the results are unpredictable. For more information, refer to the gsave command.

Syntax

grestore()

Argument

None

Code Sample Example

See "GSave (procedure)" (page 567).

GSave (procedure)

This command saves all current system parameters, which can later be restored using the grestore command. By bracketing

parts of your PlanetPress Talk programs with gsave/grestore commands, you can make sure the current system state is

preserved and remains unaffected by whatever operations your program executes. For instance, each PlanetPress object,

once converted to its PlanetPress Talk scripting language equivalent, begins with a gsave command and ends with a gre-

store, thus ensuring objects do not interfere with each other, or with the system.

The system parameters gsave saves include current line width, current stroke color, and current fill color.
