small correction: \s is same as [ \t\f\r\n], and \S is opposite to \s.

there is:
if matchText(fld "fText", "\S") is false then
answer "no text in field"
end if
This one checks for any symbols that are not "whitespace" of any kind
(\S is same as [ \t\f\r\n]).

I wonder, isn't there a way to use regular expressions to check for

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
André
