Using Easytrieve to achieve COBOL INSPECT … REPLACE functionality

Easytrieve Report Generator
Issue/Introduction
Have you ever asked the following questions....
Does Easytrieve Report Generator have the equivalent of the COBOL INSPECT...REPLACE statement?
Does Easytrieve Report Generator have a built in function that will do a search and replace?
Does Easytrieve Report Generator have a statement that will change lowercase to uppercase?
Please see the Resolution for two solutions to answer each of those questions.
Environment
Easytrieve Report Generator, release 11.6
Resolution
The uppercase/lowercase solution makes the change by adding +64 to each letter and the other one accomplishes the same end by "OR ing" a hex '40'. This solution performs a similar function to the COBOL INSPECT...REPLACE statement and can be altered to meet your individual needs.
This job makes the change by adding +64 to each letter:
