Re: Replace 1 Char with 3Char's

As in the case of replacing one string with a longer one - you have to accommodate having several of the search string - so you can't pull in data to the full extent of the variable, because of potential overflow. So to replace 1 character with 3, and to guarantee no overflow, you read 1/3 of the length, I think. That's extreme and probably never going to happen in the real world - you at least have the 2 characters of the element closure between them - this is too messy to deal with - someone else can work the calculations, thank you very much!!!

So we are back to - use sed!!! Just learn how to manage regular expressions.

If you CAN deal with a full variable and writing it back out to a
different stream file, I like using the SQL replace function -
that replaces all instances of the search string with the
replacement value - very cool. Just use a SET statement.

RPG's replace() can do the job, so long as you do it in a loop
that uses somewhere around the last found position as the start
from value in a loop. SQL is so much easier!!

Of course each implementation will have potential difficulties. Just be sure to [know how to] deal with the potential or actual truncation [sqlwarn ??] issue due to expansion of the data in a column or variable. :-)
