Where you use expressions
An InfoMaker expression is a combination of data, operators, and
functions that, when evaluated, results in a value. An expression can
include column names, operators, functions, and constants such as
numbers and text strings.
For information about functions that you can use in expressions, see
“Using DataWindow expression and InfoMaker functions” on page 629,
or look up the function you want in online Help.
