Environment

Release:
Component: OPSMVS

Resolution

The syntax of the OPSTHRSH function is :

rtvl=OPSTHRSH('function',interval,['criteria'],[criteria_startpos],[mlwto_line_num])

Specifying a line number for a MLWTO is most times to check that some characters are present on that line, which would be the 'C' criteria function, not asid ('A') function.
If specifying a C (criteria) then it's needed to specify what to check and if it's an A (asid) a line number isnt necessary.

This works :
    tran_val = opsthrsh('C','43200',word(msg.text.2,2),,2)
