SETVAR
Assigns values to MPE/iX variables. (Native Mode)
Syntax
SETVAR varname{ <space> , ; } expression
Parameters
varname The variable that is to be set to a value.
expression The expression that is evaluated and assigned to varname.
Operation Notes
This command assigns values to MPE/iX variables. Variable names may be any
combination of letters and numbers plus the underbar character, up to a total of 255
characters. Variables must start with a letter or the underbar character.
The expression parameter may be an MPE/iX expression, a Boolean, integer, or string value,
or the name of another variable. If expression consists of elements and operators MPE/iX
accepts ('abc' + 'cd' or 2*5+1), SETVAR will evaluate it. The operators defined in Table
7-1 may be used in expression.
