PM30653: for loop does not complete expected iterations

APAR status

• Closed as program error.

Error description

• User has a for loop as follows:
  for(count from 1 to StrLib.characterLen(StrLib.clip(tempData))
  by 1)
  ...
  
  
  tempData is a String variable with a number ? 1 of non-blank
  characters,
  and does not chage in the body of the loop.
  
  At runtime, the loop iterates only once.

  The problem was that the temporary variables used by part of
  the FOR statement (this is not the case for other parts of
  the FOR statement) were being placed in the statement level
  temporary variable memory area, instead of the function
  level. The statement level area are only around for a
  statement, and the next statement would redefine them and
  overlay the values. The function level area is available for
  the entire function instead. The problem was that the for
  statement can contain other statements within it, and if any
  of those happened to use statement level variables, then it
  overlaid the value that the for statement was expecting to
  keep around.
  

Problem conclusion

• The solution was to place the TO part of the FOR statement's
  temporary variables at the function level instead, thus
  preserving the value.
