child clip in turn then calls/uses) a custom function does so not via clip
but via function name:
^!If ^%Index% > ^%Count% EndLoop
^!IfTrue ^$IsEmpty(^%FieldName%)$ StartLoop
That particular (sub routine) clip is near the bottom of PAD.clb
Earlier, I'd overlooked the possibility of custom function.
I never got much into custom function. I long since learned enough of Perl
which happens to integrate well/nicely with Notetab.
Learning curve for Perl (EZ stuff is EZ, happens quick in Perl) but to get to
intermediate to advanced I found learn curve higher and longer than NTB clip.
But I find that Perl uses way less code than clip. And (after some Perl
experience) I find Perl significantly easier to track/follow/decipher than
clip (for example, the PAD.clb to track/follow *understand* what makes it
tick, how it does what it does) (decipher, key, *access* myself *into* it).
Idiomatic Perl. get to know it and then now I got it. A *very* expressive
language -- so much so that some do not like it because of the height of its
expressivenes. I experience Perl as fun!
But this is me. I've no idea if it's consensus of others or not. (obviously
one needs to Perl in order to comment).
So I (for myself) just write a Perl script/clip rather than a NTB custom
And I didn't see a prob with:
; 4 speed and not see it happen
^!Toolbar "new document"
; dump var's content to doc here
; back into var
; close discard doc here
; got what I wanted done onto my var's content
Notetab lets us choose. We each get to do it how chosen. No prob with that!
Must be good news!
And a custom function only needs Notetab, not needs perl installed in the case
of sharing clip library with other Notetab users.
