JR33753: SUBSTRING FUNCTION [] FAILS IN 7.5.2 WHEN THERE IS A NEGATIVE VALUE IN THE RESULT (ECASE 120507)

APAR status

• Closed as program error.

Error description

• Text from ecase 120507:
  The substring function [] fails in 7.5.2 when there is a
  negative value in the result. The help shows that it would
  return a value 0 if the substring results in negative or zero
  value.
  The 7.1 version behaves correctly but 7.5.2 gives
  compilation errors. Also during runtime when there are
  variables assigned and
  if the value is zero then segment violation errors occur.
  
  The exact error is: ##E IIS-DSEE-TFFN-00005 16:00:13(009)
  <transform> Error
  when checking composite operator: The argument value in
  function substring_1,
  [line 23, character 47], is less than the lower limit of 0.
  
  Job that demonstrates problem is in testcase directory.
