The JS7 - If Instruction applies different types of error handling depending on the return code reported by the failed job:

Explanation:

• Within the Retry Block the JS7 - If Instruction is used to check the return code value, This value is available from the built-in $returnCode variable.
• The first If Instruction excludes by use of the $returnCode != 0 predicate that any successful orders are excluded from the nested If Instruction. For details about predicates, see JS7 - Expressions for Variables.
• The second If Instruction determines the error handling by use of the $returnCode == 1 predicate which gives two options:
  • if the return code value is 1 then the left branch (true) of the If Instruction is used,
  • for any other return code values the right branch (false) is used.
  This is achieved by use of a predicate that checks the built-in $returnCode variable, see JS7 - Expressions for Variables
  • .
• Subsequently we find two occurrences of a JS7 - Fail Instruction.
