Visual Basic Note
The result is a C-style string, terminated by an ASCII null character. It can be converted to a Visual Basic string by counting the number of characters upto but excluding the terminating null, then performing:
VBstring = LEFT$(subType, character_count).
Remarks
The description obtained by this function is a logical one; a physical description indicating the number of discrete pads in the attenuator can be obtained using pipx40_getSubType.
