If the data will have only a single matching line, then:

   put me into N
   put fld "ProcListField" into tData
   set wholematches to true
   put line lineoffset(N,tData) of tData & cr after fld "summary"

If I understand what you want to do, this should accomplish the same 
thing without using a repeat loop.

If the goal is not necessarily to put data in the summary field, but 
rather just to hilite a line in the ProcListField field, then replace 
the last line above with:

   select line lineoffset(N,tData) of fld "procListField"

If the lineoffset is 0, then no lines will hilite, which is usually the 
correct behavior.

If your data may have more than one line that will match and you want to 
find them all, then you do need a repeat loop. You can repeat the 
lineoffset search and add a "skip" parameter -- see the docs for examples.
