   The Mac graphic environment is very different from the one of IBM
mini-systems (like old AS400). Yes, this is well-known. But, although the
many advantages of our Mac, some little feature, especially for commercial
purposes, is not present.
   In Macintosh, the editing of standard fields, for example, rarely can be
controlled "as-you-type", but only checked after the text is completely
entered. Thus, also in HyperCard.
   AutoCheck is an XFCN that, involving the "keyDown" hyperTalk function,
allows a "char-by-char" control of the text you type on a field; you can
decide to enter only numbers, letters, regular dates, formatted text, or
any group of predefined chars. The entered char can be automatically
modified (upper case, lower case, initial caps) and the total string lenght
can be limited to any number of chars.
