Customizing Features for Your Practice
A function is a special form of an expression that performs a complex calculation or action before returning its value.
Functions expand the scope of what a PracticeScript expression can tell you. Using a function such as Today() combined with a comparison operator such as = enables you to find out if certain transactions were posted on the current date. The PracticeScript variable Ledger.SvcDate represents the service date of a ledger transaction.
The expression: Ledger.SvcDate = Today() evaluates to TRUE (1) if the transaction contains the current date.
The syntax of a function is similar to that of a variable. It differs from a variable in that it is always followed immediately by an expression, or parameter, enclosed in parentheses. A parameter supplies the information that a function uses to make its calculation. Some functions have optional parameters.
If you use a numerical expression that represents a different date, the function evaluates to the first of the month of the alternative date.
