UPPER
Purpose
This is a non-SAA instruction provided in REXX/CICS.
UPPER
variable
;
UPPER translates the contents of one or more variables to uppercase. The variables are translated in
sequence from left to right.
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 page 122.)
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 signalled 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.
