Re: PERFORM "tab" moves?

An untried suggestion: If you can modify the terminals so that shift-tab sends out the same signal as up-arrow, you might have something. Or ... maybe modifying TERMCAP so that it thinks the shift-tab signal is an up arrow (ku=whatever (?)) might do the trick. And ... even *with* 4GL, you need to make sure that shift-tab is sending out a signal different than plain-ole-tab, which in my experience means you have a 50-50 chance. And even then the coding is something of a chore: # the signal sent by shift_tab has be defined as # function key F31 (kU) in $TERMCAP INPUT .... ON KEY (F31) NEXT FIELD PREVIOUS Will work in most cases, although if you have a lot of tricky intra-field dependacies (like don't go into field b unless field a is filled in), the code gets thicker. Does it sound like I've had to do this before? "Yesssss, I have!" ======================================================================= Dennis J.
