MessageBox function and statement (LotusScript® Language)
Displays a message in a message box and waits for user acknowledgment. The function form returns a value corresponding to the button the user presses.
Function Syntax
MessageBox ( message [ , [ buttons + icon + default + mode ] [ , boxTitle ] ] )
Statement Syntax
MessageBox message [ , [ buttons + icon + default + mode ] [ , boxTitle ] ]
The MessageBox function and statement are identical, except that only the function has a return value.
MsgBox is acceptable in place of MessageBox.

Usage
The valid values for the buttons, icon, default, and mode elements listed in the preceding tables are defined as constants in the file LSCONST.LSS. If you want to use the constants instead of numbers, include this file in your script.
The HCL software where you are running LotusScript® may allow longer strings than described preceding for message and boxTitle. LotusScript® will support longer strings for these items if the HCL software does.
Use the newline character to force line breaks in the message element. Or use vertical bars or braces to specify a multiline string. If you don't force line breaks, the text wraps automatically in the message box.
If you are using LotusScript® from within Notes®, note that the MessageBox function writes to:
- A dialog box when executing in the foreground on a Notes® client. The user clicks OK, Cancel, Abort, Retry, Yes, or No to continue.
- NOTES.LOG when executing on a Domino® server without pausing or as a scheduled agent in the Notes® client.
