Greetings all. I have searched a lot before posting this (including "Learning J", "Primer", etc.). I want to have a character string display when a script loads that provides information to the script user. E.g., 'F is a dyadic verb, right arg date1, left arg date2, both dates single numeric ddmmyyyy.' In APL I used to do this with quadLX (latent expression) which displayed when the workspace was loaded. But no matter what I do in a script--mention 'string', OR banner=:'string' (then mention banner on next line), OR define an explicit verb banner=: 0 : 0 (and then call banner)--the 'string' will not display when the script is loaded (as with quadLX). I just can't spend any more time experimenting. There's a trick to this in J. Can anyone provide any help with this simple problem?
