Boolean Values

There are two numeric values in the CSPro language that translate to boolean values as used in other programming languages. The value true is equivalent to 1 and the value false is equivalent to 0. Note that you need to be cautious when using true in conditional expressions, as a conditional expression is true if it is neither zero nor special, but comparing something with true is true only if the compared value is 1. That is:
numeric value = 2;

if value then
    errmsg("This will be displayed");
endif;

if value = true then
    errmsg("This will not be displayed");
endif;
