Is there any built-in function to search for parts of a string? If we, for example, have the string "fivewordswrittenasone" and want to search to see if the substring "words" can be found therein? That is, I am looking for a function that relates to @wfind as @mid relates to @wmid and thus would return the same as the code below.

Code: Select all

%str="fivewordswrittenasone"
%sub="words"

!strlen=@len(%str)
!sublen=@len(%sub)

for !i=1 to !strlen-!sublen+1
  %piece=@mid(%str,!i,!sublen)
  if %piece=%sub then
    %return=%piece
    exitloop
  endif
next

I am not sure if this is what you want, but you can try the following:

Code: Select all

!return = @instr(%str,%sub)

which will yield 5. If %sub had not existed in the base string %str, then it would have returned zero.

The following will give you the same result as your code:

Code: Select all

%return = @mid(%str,@instr(%str,%sub),@length(%sub))

That was exactly what I was looking for :-) Thank you!
