96E4 PROC

Submitted by Steve Fewell

Description:

Set the BASIC Text Pointer B to the BASIC Text Pointer A value (so that both pointers now point to the location after
the PROC-Keyword.
Set A to #&F2 (the PROC-token value), so that the &B019 (FN) routine will know that we are handling a PROCedure
call.

Call the FN routine (&B019) to evaluate the subroutine name and carry out the call to the subroutine.

Now, the PROCedure has been executed, and the BASIC and 6502 stacks have been restored to their original states (before
the call).
Call routine &9B96 to check for the end of Statement ('Syntax error' is issued if the statement end was not found)
as the program statement must be terminated by ':', carriage return or 'ELSE-token' character.

Jump to &9005 to start executing the next program statement (after the PROC call).
