PM56395: AFTER EDITING A CICS REXX PROGRAM THE FILE COMMAND TO STORE CAUSES A DFHSM0102 STORAGE VIOLATION (CODE X'0D11')

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• It looks like a problem in CICRFS00 when the REXX program
  has a blank line at the end, and that line maps to the end
  of the buffer that has just been GETMAINed to hold the data.
  

Local fix

• Insert a series of blank lines at the end of the program
  instead of one and FILE should works OK.

  ****************************************************************
  The problem is due to an overlay that is caused by CICREXD
  module CICRFS00. The code is building a buffer of data using
  task storage that has just been GETMAINed, and it is copying
  the content of a Rexx stem variable into it. The code does
  not take into account the fact that the length of any variable
  may be zero, and that results in executing an MVC instruction
  with a length of 256 bytes (X'FF'+1). This can cause an overlay
  of the trailing SAA of the buffer and the storage violation.

Problem conclusion

• CICRFS00 has been changed to avoid the storage overlay.
