FND_MESSAGE.CLEAR	Clears the message stack of all the messages
FND_MESSAGE.DEBUG	Immediately displays the string passed to it as input parameter
FND_MESSAGE.ERASE	Clears the oracle Forms status line
FND_MESSAGE.ERROR	Displays an error message in an Oracle Forms modal window or a concurrent program log file. (Example: "Invalid value entered."). It takes its message from the stack, displays the message, and then clears all the messages from the message stack
FND_MESSAGE.GET	Retrieves a translated and token–substituted message from the message stack and then clears that message from the message stack. This could be used for getting a translated message for a forms built–in or other function. Assumes you have already called FND_MESSAGE.SET_NAME and, if necessary, FND_MESSAGE.SET_TOKEN. It returns up to 2000 bytes of message
FND_MESSAGE.HINT	Displays a message in the Oracle Forms status line. It takes its message from the stack, displays the message, and then clears that message from the message stack. The user may still need to acknowledge the message if another message immediately comes onto the message line
FND_MESSAGE.QUESTION	Displays a message and up to three buttons in an Oracle Forms modal window. (Example: "Please choose one of the following actions: ") It takes its message from the stack, and clears that message. After the user selects a button, It returns the number of the button selected. For each button, you must define or use an existing message in Message Dictionary (under the Oracle Application Object Library application) that contains the text of the button. This routine looks for your button name message in the Oracle Application Object Library messages, so when you define your message, you must associate it with Oracle Application Object Library (the "FND" application) instead of your application
FND_MESSAGE.RETRIEVE	Retrieves a message from the database server, translates and substitutes tokens, and sets the message on the message stack
FND_MESSAGE.SET_NAME	Retrieves your message from Message Dictionary and sets it on the message stack. You call it once for each message you use in your client–side PL/SQL procedure. You must call this procedure before you call FND_MESSAGE.SET_TOKEN
FND_MESSAGE.SET_STRING	Takes an input string and sets it directly on the message stack. The string does not need to be defined in the Messages window. These strings may be hard coded into the form and are not translated like messages defined in Message Dictionary
FND_MESSAGE.SET_TOKEN	Substitutes a message token with a value you specify. You call FND_MESSAGE.SET_TOKEN once for each token/value pair in a message. The optional translate parameter can be set to TRUE to indicate that the value should be translated before substitution. (The value should be translated if it is, itself, a Message Dictionary message name.)
FND_MESSAGE.SHOW	Displays an informational message in an Oracle Forms modal window or a concurrent program log file. (Example: "To complete this function, please enter the following... "). It takes its message from the stack, displays the message, and then clears only that message from the message stack
FND_MESSAGE.WARN	Displays a warning message in an Oracle Forms modal window and allows the user to either accept or cancel the current operation. (Example: "Do you wish to proceed with the current operation?") FND_MESSAGE.WARN returns TRUE if the user accepts the message (that is, clicks OK), or FALSE if the user cancels. It takes its message from the stack, displays the message, and clears that message from the message stack
