Declaration

AskMsgNumber(question : Text; title : optional text; default : optional numeric)

Description

Shows a message box with specified title, question and a textbox containing the default value, if any. It returns the number entered by the user into the text box.

If the default is specified, it is displayed using the number format for the object containing the call. When not specified, the entry box will be blank initially. By setting the number format for the variable containing the call to date, a date entry is accepted.

The [OK] button is active only when a valid number has been entered. The [Cancel] button aborts the current computation.

The message box appears only when this function is evaluated. Since Analytica caches results once they are computed, if you embed this in a variable, you will not see the question every time you view the result. To trigger the question again, you must change something upstream that the variable depends on, so the result is invalidated. If you place it inside a button script, you would see it everytime the button is pressed.
