Q: How do I fix S0C7 Data Exception ABEND?

Answer:

S0C7 occurs when the program tries to perform arithmetic on non-numeric data.

Common Causes:

  1. Uninitialized numeric fields (contains spaces/garbage)
  2. Moving alphanumeric data to numeric field
  3. Reading file with wrong record layout
  4. Array subscript accessing wrong memory

How to Fix:

  1. Initialize all numeric fields to ZEROS
  2. Validate input before arithmetic
  3. Check file layouts match
  4. Use DISPLAY to debug field contents
* Always initialize
INITIALIZE WS-RECORD.
MOVE ZEROS TO WS-AMOUNT.

* Validate before use
IF WS-INPUT IS NUMERIC
    COMPUTE WS-RESULT = WS-INPUT * 2
END-IF.

Q: What causes S0C7 in batch?

Answer:
S0C7 is data exception - non-numeric in numeric field. Check: input file data quality, initialize variables, correct REDEFINES, field alignment. Use OFFSET in dump to find statement. LE CEEDUMP shows data values. Common with new programs.

Q: Explain CALL statement and parameters

Answer:
CALL invokes subprogram: CALL 'SUBPROG' USING param-1 param-2. BY REFERENCE (default) passes address. BY CONTENT passes copy. BY VALUE passes value (for C). ON EXCEPTION handles load failures. CANCEL releases memory.
