screen

screen save|show|free num

This command allows the user to save the contents of the display window into a buffer in memory, and also to restore a saved buffer to the current display at any time. This command will work in double buffer mode and was written to facilitate animations when working interactively with GrADS. The options are as follows:

save
Saves the contents of the display screen into memory as buffer # num.

show

Draws the contents of buffer # num to the screen.

free

Releases the contents of buffer # num from memory.

Usage Notes

This command does not work in batch mode, or in version 2.1+ when Cairo is enabled.
