Block Program Data
Definite length arbitrary block response data is defined in section
8.7.9.2 of IEEE Standard 488.2-1992, IEEE Standard Codes, Formats,
Protocols and Common Commands for Use with ANSI/IEEE St d
488.1-1987. New York, NY11992 .
<definite length block >
It allows data to be transmitted over the system interface as a series o f
8 bit data bytes . This element is particularly useful for sending larg e
quantities of data, 8 bit extended ASCII codes, or other data that ar e
not able to be directly displayed .
