Issue/Introduction

Is it possible to search for a hex-character like x'00' in members of a Librarian Master file?

Environment

Release 4.4 

Resolution

The FAIRSCAN user contributed routine can do such a search.  FAIRSCAN can perform hex-value searches as well as character string searches.

The FAIRSCAN routine must first be installed.  For more information on how to install and use FAIRSCAN, see :

User Contributed Routine FAIRSCAN

 

Here a template to run the FAIRSCAN program searching for a X'00' in any members of the Masterfile.
In order to change the search value in front of the scan #$# delimiter string, use the ISPF HEX ON editor command. 

...
    //SCAN EXEC PGM=FAIRSCAN,PARM='NRJS,NJTA'
    //STEPLIB DD DISP=SHR,DSN=<your.LIBR.CSIQLINK>
    //MASTER DD DISP=SHR,DSN=<your.master.file>
    //PRINTOUT DD SYSOUT=*
    //SYSOUT DD SYSOUT=*
    //CARDIN DD *
    -SCAN .#$#
    -COLM 001 072
    ...

Data for the control cards starts at column 11, the SCAN literal MUST be terminated by #$#.

The -SCAN line above looks in hex like:

-SCAN      #$#
