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.

Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users of SUPERC utility from HLASM Toolkit   *
    *                 for z/OS, z/VM and z/VSE.                    *
    ****************************************************************
    * PROBLEM DESCRIPTION: When SUPERC is used with the            *
    *                      NFOCUS/OFOCUS or NEXCLUDE/OEXCLUDE      *
    *                      options and an option such as DPBLKCL   *
    *                      is specified which suppresses           *
    *                      processing of blank lines, changed      *
    *                      lines in the listing are truncated by   *
    *                      the width of the excluded columns.      *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    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.
