HyperCard sends the
enterInField command to a field when the user presses Enter and the insertion point is in the field.
command saves the results of any changes the user or a handler makes to a field and closes the field.
HyperCard sends a
closeField message if the user made changes to the text or sends
exitField if the user did not make any changes).
You can handle the
enterInField message as follows:
Any return-separated list of built-in commands, user-defined handlers, or keywords that are part of a message or function handler.
put "Hello world" -- built-in command
get total(field 1) -- function call
global HelpInfo -- keyword
