Here is a program titled SRCHREPL (search and replace).
The original was by Alan Weis.
Inputs: Level 3: string
Level 2: search string
Level 1: replace string
Outputs: Level 1: modified string from level 3
All occurances of the level 2 string were replaced by the
level 1 string. At least thats how it was supposed to work.
Actually, only the first character of the string in level
2 was replaced with the level 1 string.
Example: Level 3: "123ABC456"
Level 2: "ABC"
Level 1: "TEST"
Actual Result: Level 1: "123TESTBC456"
Desired Result: Level 1: "123TEST456"
The "BC" should have cut along with the "A".
This version corrects the problem. To strip characters
from the original, just place a null string, "", on
level 1. Note that MULTI is required. It is listed here
as well if you don't already have it. Apologies to ALAN or
someone else if a corrected and/or faster version has
already been posted!
