Parameter is divided into two parts, the Test and the Result if True. The test comes prior to the keyword of Then and the Result if True comes after.

Description:

The test can take two forms:

1. Field/Expression (Boolean)
2. Field/Value Condition Field/Value/Expression (Condition)

When Boolean:

• Field/Expression is a boolean test such that if the Field/Expression is/returns empty it is False, and if it has any data it is True
• If an Expression is used, it must be surrounded with ( ) to be evaluated
• The Not operator can be placed in front of a boolean test to reverse the boolean logic. In the case of an Expression, Not must come before the ( ) eg. If Not ( )

When Condition:

• The list of Condition operators, Text and Math, are generic across other If commands in MOX, and are documented on the Syntax page. Note the separate list of Math vs. Text operators; the Math operators are doubled-up
• When testing a Field/Value against another Field/Value, ( ) must not be used
• Testing a Field/Value against an Expression, or an Expression against another Expression. Expressions on the left side of the Condition operator may not contain any of the symbols used by the list of Condition operators

Examples:

One = "y"
Two = ""

[If] One
[If] Not One
[If] Two     Then "Yes"
[If] Not Two Then "Yes"

OneIsOne  [If] One = One
OneNotOne [If] One <> One
OneIsTwo  [If] One = Two
OneNotTwo [If] One <> Two

TwoSolve      [If] Two = $SessionIsBad Then "Yes"
IsExpression  [If] $SessionIsBad Then "Yes"
NotExpression [If] Not $SessionIsBad

Never         [If] $Today = ($Greg (%Greg + 123)) Then "Never"
