A small remark (Re: Advice with HP41 Card Reader) Message #5 Posted by Luiz C. Vieira (Brazil) on 5 Apr 2012, 11:35 a.m., in response to message #1 by John Abbott (S. Africa)
Hi.
The procedure, as already agreed by M. Joury, is correct. You just need to keep in mind that if you remove the 'END' statement of an existing program and, as a consequence, it merges with another existing program, its functionality will be probably corrupted. In most cases, the 'END' statement also plays the role of a RTN (return of a subroutine) or a single STOP, meaning that a running program that finds the 'END' statement will either stop running or cause a return to a subroutine call (XEQ). In any case, once you remove the 'END' statement it is a good idea to either replace it with a RTN (preferable) or a STOP, so the program will respond accordingly. These additional steps will not interfere in the original program operation.
Cheers.
