 That's right - parentheses are not free in Scheme scripting, every opening

Thanks, both of you for clarifications.
Not sure where I saw the print but it seems to work:

 (define (find-dot txt txtLen offset) (print foo) xyz pqr) (find-dot 
 abcd.ef 7 1)
find-dotfoo
pqr
 (define (find-dot txt txtLen offset) (display foo) xyz pqr) (find-dot 
 abcd.ef 7 1)
find-dotfoopqr

The function itself seems to be accepted.
It appears the difference between using display and using print 
is that print outputs enclosing double quotes plus trailing newline;
display outputs the unadorned string and no trailing newline.

   First, you wrapped the whole thing in ( ). Drop the leading and trailing
   parentheses.
  
   Second, that is a line of Scheme code and Scheme does not contain a print
   function. You probably meant to use display. Also keep in mind that the
   display function only takes a string so you may first need to convert 
 what
   you pass it to a string.

[Gimp-user] script-fu: illegal function?

2012-09-17 Thread Gary Aitken 
When I try the following in the script-fu console:

((define (find-dot txt txtLen offset) (print foo)) (find-dot abcd.ef 7 1))
foo
Error: illegal function 

The find-dot macro obviously exists and is being executed.
So what is the illegal function it is complaining about?

Thanks
