PM89747: TURNING ON THE DPBLCK OPTION IN SUPERC TRUNCATES SOME OUTPUT IN COLUMN RANGE 40-50 EVEN WITH LONGLN OPTION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The original complaint was:
  Super C is truncating output in compare files when
       using LONGLN option, which provides for an output
       listing width of 203 characters.
  
  Further investigation showed that Super C alone was working OK
  and that the user was calling SuperC from their own exec and
  that turning on the DPBLCK option to ASMFSUPC causes the
  truncation to appear on z/VM.

  *                      options and an option such as DPBLKCL   *

  *                      lines in the listing are truncated by   *
  *                      the width of the excluded columns.      *

  ****************************************************************
  SuperC focus/exclude processing logic during input processing
  builds the string of data to be compared in a different way from
  normal processing.  If any option was specified which might
  involve checking for blank lines, such as the DPBLKCL option or
  any of the programming-language "don't process" options,
  special-case logic would call the routine to build the compare
  string both during normal compare processing and also at other
  times to allow checking for blank lines.  Part of this
  processing modified the input length to reflect the assembled
  compare string, which affected the print output.  Also, the
  special-case code caused some of the normal logic to be
  bypassed, including the DPBLKCL check for blank lines and
  processing of the ANYC option for case-insensitive comparisons.
  

Problem conclusion

• The SuperC logic to support the special-case combination of
  excluded columns and don't-process line options such as DPBLKCL
  has been modified to ensure that the listing data is not
  truncated and the DPBLKCL and ANYC options are correctly
  supported.
