SetScriptVariable

The SetScriptVariable function sets the specified script variable for the specifed script system to the value of the input parameter.

FUNCTION SetScriptVariable (script: ScriptCode; selector: Integer; 
                            param: LongInt): OSErr;

script

A value that specifies the script system whose variable you are setting.

selector

A value that specifies a particular script variable.

param

The new value for the specified script variable.

DESCRIPTION

The actual values to be assigned may be long integers, standard integers, or signed bytes. If the value is not a long integer, you must store it in the low-order word or byte of the param parameter and set the unused bytes to 0.

The SetScriptVariable function returns the value smBadVerb if the selector is not valid, and smBadScript if the script is invalid. Otherwise, it returns 0 (noErr).

To specify the script variable whose value you wish to change, use one of the
selector constants listed on page 6-65. To specify the script system, use one of
the script-code constants listed on page 6-52.

RESULT CODES

noErr	0	No error
smBadVerb	-1	Invalid selector passed to the routine
smBadScript	-2	Invalid script code passed to the routine
