Boolean
In Boolean expressions:
ƒ Zero is interpreted as FALSE and all other values are interpreted as
TRUE.
ƒ Boolean expressions that evaluate to FALSE have a value of 0.
• Boolean expressions that evaluate to TRUE have a value of 1.
Boolean expressions consist of string and numeric expressions that
evaluate to a TRUE or FALSE value. Often, a Boolean comparison
operator is used, for example:
IF %A + %B == 4
This is not always the case. For example:
IF %A //same as IF %A == TRUE
To stretch the realm of Boolean expression, consider the following
example:
%Sum := (%A == %B) + 4
//%Sum will always be either 4 or 5
// (%A == %B) will always evaluate to true (1)
// or false (0).
