Takes a single Field name, with an optional Not operator, followed by the conditional statement

Description:

FieldName is used as a boolean test where if the field is empty it is False and if it has any data it is True. The optional Not operator may be used to reverse this logic. The statement that follows the Then will be skipped if the evaluation is False. If / Then may be used within an If / End If block.

For TopQuery assignments, do not use If / Then, use the [If] assignment operator instead

Example:

[Pull] Req.IsPost Req.Mode

If Not ($SessionIsBad)
    If     Req.IsPost Then Update "MemTab.Person"
    If Not Req.IsPost Then Get    "MemTab.Person"

    NewName [If] Req.Mode = "Post" Then (FirstName && LastName)
End If
