REXX – CHANGE UPPER TO LOWER CASE

In REXX you do not have a direct function to change UPPER case characters to LOWER case or Vice versa.

To achieve this you can make use of TRANSLATE function.

/*** REXX ***/

SAY ‘PLEASE ENTER A STRING’

PULL STRING

UPPER = ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’

lower = ‘abcdefghijklmnopqrstuvwxyz’

FINAL = TRANSLATE(STRING,LOWER,UPPER)

SAY FINAL

The above REXX would convert all UPPER CASE to LOWER case.

And to convert LOWER CASE to UPPER CASE change the TRANSLATE function as below.

FINAL = TRANSLATE(STRING,UPPER,LOWER)
