HP-41C keyboard less reactive in USER mode?

[pascal_meheut]

Hi,
I'm still experiencing with my HP-41CX and I've noticed that in USER mode, it is less reactive.
I've assigned a few keys, -, +, x, /, 7, 8, 9, 4 and R/S.

When I press 1/x in normal mode, it is instant. But in USER mode, it takes more than 1 sec.

Is this normal? Because it surely seems strange.

that is normal behavior when your calculator's program pointer points to somewhere in a large PGM. then, your HP-41CX is trying to find labels LBL A .. LBL E and labels LBL a .. LBL e, which are automatically associated with the top row keys. to get rid of the delayed response, do a [GTO] [.] [.] to go to the .END. of the program. that should fix it.

Is this because the key assignment is now stored in program memory which has to searched first? In lieu of going to the main hard coded function.

Thanks. This is it.

To get around local labels (A..J, a..e) scan latency, I normally put all these labels nears the top of my programs.

Code:

| 01 LBL "LLDEMO"     | 07 LBL A            | 60 LBL 20           |
| 02 "HELLO WORLD"    | 08 XEQ 20           |    ...              |
| 03 AVIEW            | 09 GTO 99           | 78 RTN              |
| 04 LBL 99           | 10 LBL B            | 79 LBL 21           |
| 05 STOP             | 11 GTO 21           |    ...              |
| 06 GTO 99           |    ...              | 92 GTO 99           |
