GRAPH

Starts a graphics program.

Syntax

GRAPH expression [ RESET|CLOSE] [INVISIBLE] [BACKGROUND]

Parameters

expression

 

A character string, or expression that evaluates to a character string. The content of the string is passed to the graphics program call (e.g., parameters). If no parameters are required, specify the null string.

 

RESET

 

Flushes all internal data buffers to disk.

 

CLOSE

 

Flushes all internal data buffers to disk, and closes all files not currently in use.

 

INVISIBLE

 

Executes the graphics program without affecting the screen display.

 

BACKGROUND

 

Executes the graphics program asynchronously while Zim continues to run. You can continue working, and have a number of graphics sessions running concurrently.

 

Note: BACKGROUND is ignored in some operating environments.

Comments

The value of the system variable $Graphics identifies the graphics program to be run. If $Graphics has not been assigned a value, the default value is used.

When you exit a graphics program that was not run in the BACKGROUND, execution of your application program resumes following the call to the graphics program.
