Processing to run against each highlighted line of a browse lookup

[Richard Kreiss]

I thought his original post wanted an option to be run without user input.

If course he could always use an output process which selects just the records need to be processed.  This avoids a lot of programming issues.

Of course using an array top hold the record information is most likely the simplest solution.  If a user needs to start the operation then the browse exit keys could start the process.

The user could select the records to be processed by loading them into an array and then starting the posting process or whatever is to be done to those records. Or all of the records could be loaded into an array by doing this with the drop option sub-routine.
