PML 2 Expressions

PML 2 introduces enhanced facilities for expressions in IF and DO commands and when giving a PML variable a value using = assignment.

For example, the value of a PML variable can be used by giving the variable name as the expression to the right of =:

!SavedValue = !Number

Users familiar with PML 1 should note the absence of $ preceding the variable name. These new expressions do not need to be enclosed in ( ) parentheses:

!NewValue = !OldValue + 1

PML 2 expressions:

• May be of any complexity.

• May contain calls to PML functions and methods.

• May include form gadget values (described later), and object members and methods. For example:

  !NewValue = !!MyFunction(!OldValue) * !!Form.Gadget.Val / !MyArray.Method()
