Hello
Thanks to all who paid attention to my question
Quite a nice number of ways (mainly variations around counting the
number of words)
best regards from Grenoble

P.S. Once again I did not receive a couple of messages; those from
Craig ; I saw they were sent thanks to the answers, and on the archives
One more mystery of e-mail ?

This assumes what you need is whether text is in the field...
function isEmpty pFld

Bonjour,
I need to test if a given list field in a stack contains some values
or if it is empty.
Well, by "empty" I mean that the field contains not any word or
number. But it happens that it may include carriage returns and/or
tabs.
In such cases :
field "thisField" is empty
return false.
If there were only carriage returns, I could test if each line of the
field is empty;
indeed :
line x of fld "thisField" is empty
returns true if the only character in the line is cr
but returns false if there is at least one tab in the line.
I just tried :
if last char of fld "thisField" is empty ;-))
that seems working well ! but a bit strange and might be not
reliable ?
Is there a better trick ?
Thanks for any idea
Best regards from Grenoble
Andri
