Before you begin to modify panels, consider the following recommendations:

• Do not shorten the column headings.

  If you change the headings on the List Entry Panel, you should also change the corresponding fields and text on the selection entry panel, the VIEW and SORT Entry Panels. For Data Set, Volume, and List Applications, you should also change the corresponding fields and text on the FILTER Entry Panel. You should also change the help panels and messages that support these entry panels and the list panel.

• Make copy of the library that you modify, because the next time a link-edit or maintenance is performed on the member you have changed, your change will be lost.
• When editing ISMF libraries, do not change the NUM field in the profile and do not issue the RENUM editing command.
• You can change the wording, but you cannot change the order of the columns or the characters to the left or right of the headings. Also, you cannot add or delete columns.
• The widths of the first two columns are fixed, so any textual changes you make will not alter the size of the fields.
• You can increase the lengths of the headings, as well as modify the text, in the third through the last columns. Be sure to update the lengths associated with the text you lengthen.
  Figure 1. Column 10 of Member DGTDS08.

  /************************************************************************
  /*  Column 10: REC FMT
  /*  Length   : 5
  /************************************************************************
  DGTDS080   '5'
  ' REC '
  
  DGTDS081
  ' FMT '
  
  DGTDS082
  '(10)-'
   

  If, for example, you would like to change column 10 to say RECORD FORMAT instead of REC FMT, simply perform these tasks:

  1. Access member DGTDS08 of the MESSAGE library (see Figure 1).
  2. Enter PROFILE on the command line and verify that NUMBER is set OFF.
  3. Replace ' REC ' with 'RECORD' and replace ' FMT ' with 'FORMAT'.
  4. Replace the decimal length '5' with '6' (the new length).
  5. Pad the tag with dashes. In other words, '(10)-' would become '-(10)-'.
  6. Compare your results to Figure 2.

/************************************************************************
/*  Column 10: RECORD FORMAT
