Alphanumeric to Numeric move...
Alphanumeric value in Numeric field used in computation working perfectly fine.. actual it should abend?

Example:

05 WS-COUNT PIC 9(3) Value 0.
05 WS-COUNT1 PIC 9(3) Value 0.
05 WS-ALPHA PIC X(3) Value 'BBC'.

Move WS-ALPHA to WS-COUNT

COMPUTE WS-COUNT1 = (40 + WS-COUNT)


Not understanding the Move rules here, please advise?

What results when you try it? Provide HEX display of fields before and after the MOVE and COMPUTE.

Actually, no it should not abend. From the Enterprise COBOL Language Reference manual, referring to numeric or numeric-edited receiving fields:
Quote:
When the category of the sending item is alphanumeric, alphanumeric-edited,
national, or national-edited, the data is moved as if the sending item were
described as an unsigned integer.
So the behavior you are seeing is normal and expected PER THE MANUAL.
