Oops, sent that too soon. I find it useful often, usually when validating things, eg: select when words(f!ce_bfe) \== 1 then f!ce_err = "bfe '"f!ce_bfe"' not a single word" when \datatype(f!ce_ssn,"W") then f!ce_err = "ssn '"f!ce_ssn"' not a whole number" when \datatype(f!ce_ssx,"W") then f!ce_err = "ssx '"f!ce_ssx"' not a whole number" when \datatype(f!ce_wcn,"W") then f!ce_err = "wcn '"f!ce_wcn"' not a whole number" when \datatype(f!ce_wcx,"W") then f!ce_err = "wcx '"f!ce_wcx"' not a whole number" when \datatype(f!ce_wln,"W") then f!ce_err = "wln '"f!ce_wln"' not a whole number" when \datatype(f!ce_wlx,"W") then f!ce_err = "wlx '"f!ce_wlx"' not a whole number" when \datatype(f!ce_wld,"W") then f!ce_err = "wld '"f!ce_wld"' not a whole number" otherwise f!ce_err = "" end if f!ce_err \== "" then do f!ce_rettxt = f!ce_errpfx f!ce_err signal func_jn_chk_encp_z end (which is from a KEXX macro that's held in a library - ie a single file containing many macro definitions. The peculiar variable names - these all starting "f!ce_" - are used so that when I'm editing the whole file and look for instances of where else a var is used I can look for, eg, f!ce_<something> and not find vars used in the same way in other macros in the same file. That is, all the vars in that specific function have names that start that way, different from vars in other functions in the same file. The odd prefix also follows a naming convention I adopted according to whether the macro is one (as here) for a primary function I invented, or a utility one, or for a function that Kedit will invoke itself based on a keypress or a menu selection or a toolbar button click etc (where I don't get to choose the macro's name).)) -- Jeremy Nicoll - my opinions are my own. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
