Re: RPGLE pgm to parse a string

[AGlauser@xxxxxxxxxxxx]

What about:

/free
   myString = 'THIS_BE_A_TEST_STRING_MATEY!'

   tempIndex = %checkR('_' : myString);
   index2 = %checkR('_' : tempIndex);
 
   // make index1 be the character after the third last '_' (the first 
character you want to extract - hence the +1)
   index1 = %checkR('_' : tempIndex) + 1;


   newString = %subst(myString : index1 : index2 - index1);

/end-free


Hope this helps,
Adam

PS - I hope it was not intended, but the last email seemed awfully 
demanding (to me anyway).  This will generally make people not want to 
help you.
