UPPER

UPPER translates the contents of one or more variables to uppercase. The variables are translated in sequence from left to right.

This is a non-SAA instruction provided in REXX/CICS.

The variable is a symbol, separated from any other variables by one or more blanks or comments. Specify only simple symbols and compound symbols. See Simple Symbols.

Using this instruction is more convenient than repeatedly invoking the TRANSLATE built-in function.

Example

a1='Hello';  b1='there'
Upper a1 b1
say a1 b1     /* Displays "HELLO THERE" */
An error is signaled if a constant symbol or a stem is encountered. Using an uninitialized variable is not an error, and has no effect, except that it is trapped if the NOVALUE condition (SIGNAL ON NOVALUE) is enabled.
