155B GraphicFunction¶

Stub MON 155B (109 decimal) · Mnemonic GRAPH · Group: Input and Output Monitor Calls (manual section 2.5)

Available from: All programs (manual compatibility box)

Emulation source: src/handlers/mon_155B_GraphicFunction.c

Description¶

Executes various functions on a graphic peripheral, such as a NORDCOM terminal, a pen plotter, or a Textronix display.

Notes¶

Some functions require a delay from the calling program. See the specifications for the peripheral in use. SuspendProgram delays a program.
The old monitor call PLOT is obsolete.

Parameters¶

Name	Type	Direction	Description
`Ycoor`	INTEGER	In	The Y-coordinate of new line relative to current reference point.
`Xcoor`	INTEGER	In	The X-coordinate of new line relative to current reference point.
`Code`	INTEGER	In	Integer code.
`DeviceNo`	INTEGER	In	Logical device number.
`Func`	INTEGER	In	Function code. 0 means PLOT. 1 means PLOTS, i.e. establish reference point and/or clear a NORDCOM screen. 2 means NEWP, i.e. select pen or screen.
`ReturnValue`	INTEGER	Out	Return value. Output parameter for the PLOT function. Not used on the ND-500.

Direction: In = the program supplies the value, Out = the call returns it, In/Out = both.
