A FoxPro Format expression applied to the value that is displayed.
This can be a FoxPro Format expression like @! or @YL or a function call.
You can also use functions or methods for formatting by prefacing the name of a function/method with an = sign. However, the function MUST accept at least a single parameter (the value of the Expression) and return a string result.
Note that you specify only the the = and function/method name not the () or parameter list. Web Connection will pass the specified function a single parameter which is expression value.
Note that if you use expressions it's often easier to simply create an Expression instead and simply pass the expression.
