Sharp PC-G850VS

[Luca Puntin]

Hi,

I'm new on this forum, so I present myself.

First of all... excuse me in advance for my poor English, I'm italian and I don't like translators...
I'm a 56 yo teacher of Mechanics (practice teacher) and electonics hobbyst.

I've recently acquired a Sharp PC-G850VS directly from Japan (around 110 Euro) with the main target of PIC programming. I know that a very poor PC with PICKIT2 or 3 is more flexible, but the Sharp ultra-portable solution is somewhat fascinating...

I've downloaded the english manual (thanks to who did a so good work, translating it from Japanese and/or German), but I've got two questions about programming a PIC:

1) how can I enter the "_" character (for the __CONFIG directive to assembler) into text editor ?
2) where is the file "p16f84a.inc" located ?

About the first question, I don't see the underscore on G850 keyboard, but I don't know if there is a function like the "alt+nnn" keystroke on a PC numeric pad: what is sure is that "_" does exist into the G850: going into BASIC run mode, typing PRINT CHR$ 95 + (Enter) results in "_" visualization. But there is no "Copy and Past" to the Text editor.
I'm tempted to run a BASIC program to save a couple of "_" into Text editor working ram area, but I suppose that area is protected when reserved to editor, so a machine code (Z80 assembler) routine may be the solution.... But if someone has just programmed a PIC there must be a simpler way.

About second question, I suppose that "p16f84a.inc" is located into G850 firmware, so a bit hard to modify for change PIC model. PIC16F627 (that is declared usable) is a pin-to-pin substitute of the 16F84A, but I suppose to be difficult use internal oscillator, analog inputs an comparators that are not present into 16F84a. But it is obviously still possible do all "EQU's" into program, without use "include" assembler directive.

Bye.
