HP41CX - Naive' question - "Current File"

[Gene]

NOTE: DO NOT use this code if your extended functions plug-in module is version 1B. This can be see by doing a CAT 2 when plugged into your HP-41.

If you have a version later than 1B, such as 1C, etc. OR if you are using an HP-41CX or DM-41, then the code below is safe.




If you use RCLPT and there is no working file, the message "FL NOT FOUND" is displayed.

In a program, this code:

LBL 01
SF 25
RCLPT
FS? 25
This step is executed if there is no current file.

Is that what you need ?
