[q-lang-users] where

[Eddie R. <ed...@bm...>]

Given the following script

// strip character C from the left and right sides of a string
strip C "" = "";
strip C S = strip C $ sub S 0 (N-1) if (S!N = C) where N = #S-1;
	  = strip C $ sub S 1 N     if (S!0 = C) where N = #S-1;
	  = S                       otherwise;

Is it possible to have another type of local variable defined at the end
of a list of equations that would apply to all of them? For example, the
"where N = #S-1" is on both lines. This is not a good example, but what
if I have a list five or more equations, the same where clause on each
line seems a waste of typing. I understand that "where" should apply to
the equation that it corresponds to instead of all of them because you
might not want the local variable apply to the other equations in the
list.

I know a where clause could be applied to cond, case, and if then else.
