GOTO absolut address - is that possible?

[Darrel Taylor]

From another thread I saw he's using an 18F4550 with a USB bootloader.

So nope. No Pages to worry about.

Hi, Darrel

While on that subject ...

I use, on a 16F88 :

' If program lost

@ ORG 4094			' Pointer to the end of program
@ CLRF PCLATH			' pointer in the right page ( lol )
@ GOTO INIT 			' It's gone for another round...
'
@ END

Works and compiles fine ... BUT

No way to use Breakpoints in MPSIM when lines not commented ...

Do you have any idea about that ??? ( µChip tells ... go and see Melabs !!! - as always ... )

Hi Alain, Just curious . . . ASM comment is ; not ' yes?

Hi Alain, Just curious . . . ASM comment is ; not ' yes?

Way to go Joe!
I didn't even see that.

Can't imagine how it compiled.

Thanks Darrel 30 years of snivel service teaches you to pick fly specks out of the pepper ELSE Nazi bosses frag your reputation.

Hi, joe

YES ... looks right, but compiles and runs fine.

After all, It's a PBP program ... intelligent compiler ? lol : might be.

In fact, MPLAB accept both " ; " and " ' " ... as MPLAB Editor is set to "Basic" mode. Why not use what computers offer for ease of work ( Humour ...)

Changing " ' " to " ; " do not change anything ...

You're quite right : Manual says " line is sent verbatim" ... but, obviously, comments are not sent !!!

Ask questions and learn, Right? <br>PBP & Assembler, like mixing 10 oz alcohol and 10 oz water, you do not get 20 oz of liquid.
I read books AND this forum, sometimes experience and books do not agree. Anyway I try to help and am not embarrassed to learn from the masters.

Hi,

Here is the Melabs answer :

Below is the response that I received from MicroEngineering Labs regarding your issue:

I've found that the problem only occurs when the assembly-language jump to our INIT routine is included:

@ GOTO INIT

I'm guessing that since the INIT label isn't a label in the program source code (it is an internal label PBP creates), it is not something that can be resolved for source-level debugging.

User code should not jump to our INIT routine. If he wants to restart his program, he should declare a label in the source and use it instead.

... now just have to find WHERE to place this "dummy" label ...

ring you asap.

Ok, it's solved

Look at the "Restart" Label ... it must be placed before the very first PBP command : here, an " INTCON = " statement.

The ASM " Init " ( no underscore !!! ) label is automatically placed here by PBP in the .asm generated.

This way, all the registers are re-set to the convenient values ...
