JCL System Abend: SOC 1 and SOC 7

SYSTEM ABENDS

I am sure everyone is aware of system ABENDS. I have tried to list ABENDS for all the possible reasons. Hope you all find it useful.

SOC 1 

This abend can be faced in following situations. Rule out following possibilities:

• Any file doesn't have open statement and directly trying to read it
• The subscript it may be out of boundary for a defined COBOL table
• Review JCL for missing or misspelled DD name
• Problem in parm passed to subroutine related to addressing mode or Data mode
• Recording mode may be wrong 
• Sub program called is not found problem in dynamic link or static link
• Check load module there can be a possibility if subroutine program id and program name not same. This means bad load module.
• An uncontrolled loop moved data on top of instructions. 
• Problem can be same name for array and subroutine  

    SOC 7 

This is a data exception and can only occur when decimal (packed) instructions are used. 

• When alphanumeric data moved to packed decimal data (COMP 3).
• When Programmer use a variable, which is not defined in working storage.
• Period missing after imperative statements within AT END clause.
• Binary field in an arithmetic operation is not large enough to accept result.
• Failure to initialize a counter.
• Invalid incoming data (e.g., blanks, decimal points, or commas in a numeric field).
• Exceeding a table via a subscript (index) error, causing a reference to invalid data.
• Moving zeroes or low-values to a group field defined as numeric.
• An omitted or erroneous usage clause.
• Passing parameters between programs in the wrong order.
