TFNUM Function

The function TFNUM returns the tab field number of the current tab position. It returns zero if the form is not active, or before the first position. A program can use this to test if the user has filled in all the fields of the form. For example:

10    INPUT
20    IF TFNUM%<4 THEN 10
30    ENTER A(1), A(2), A(3), A(4)

The user presses TAB to tab to each field. Pressing TAB in the last field will cause line 30 to be executed.
