GETCURSOR inquires the Tektronix GIN device for the location pointed to by the GIN device. Return code is screen device dependent. This routine is does support all screen devices. When a device is not supported, the routine returns without doing anything. Screen device must be in the graphics mode. GETCURSOR assumes that the GIN terminator is a CR (carriage return). Note: When using an Alpha key for the return status DO NOT use the <Return> key as this will prevent the correct reading of the returned data.
