I am not sure whether MODIFY COMMAND is disabled; I think it is not. But you can edit text in an EditBox, within VFP.

Note that for commands, the COMPILE command would be required (disabled in earlier versions; available at runtime in VFP 6 SP3 and later).

However, Maltin wanted to edit a form; it is more difficult to give the end-user the interactive capabilities which you expect from a command like MODIFY FORM.
