Answer 1

When a report terminates with an error, REPORT_OBJECT_STATUS returns the value "TERMINATED_WITH_ERROR", which is 21 bytes of data, but rep_status is defined as 20 bytes. The 6502 error is due to the data not fitting the variable.
I recommend wrapping the REPORT_OBJECT_STATUS function with a SUBSTR that limits the data returned to 20 bytes, which will ensure the results fit.
For example:
rep_status := SUBSTR(REPORT_OBJECT_STATUS(v_rep), 1, 20);
