Detecting Error Occurrence using SRQ (HT Basic)

Detecting Error Occurrence using SRQ (HT Basic)
Example 9-17
using SRQ. This program is stored on the sample program disk under the
filename "srq_err.bas".
This program sets up SRQ, intentionally sends a nonexistent command for the
E4981A to generate an error, and performs error handling. In the error
handling, the program checks which error has occurred, displays the error
number and error message, and displays the "PROGRAM INTERRUPT"
message.

shows a sample program to detect the occurrence of an error
Sets the GPIB address.
Enables bit 2, bit 3, bit 4, and bit 5 of the standard event
status register and sets bit 5 of the service request enable
register to 1.
Clears the status byte register, standard event status
register, and error queue.
Sets the branch destination of the SRQ interrupt and
enables SRQ interrupt.
Selects the primary parameter and secondary parameter.
However, because the command for the secondary
parameter is wrong, an error occurs.
Processing when an error occurs. Reads out the error
number and error message of the error that has occurred.
Displays the "Error occurred!!" message, error number,
error message, and "PROGRAM INTERRUPT!!" message.
Displays the "PROGRAM DONE" Message. Notice that this
message is not displayed unless you correct and execute
the secondary parameter selection command.
