Patching: Technical Discussion ...

@ MASTER:
Long time ago you have explained me how to put a dinamic text in a MessageBox, but still I don't understand well to insert a variable number in that string.
I want to write "x inbox SMS", where x is a variable number stored in a RAM word, and "inbox SMS" is string ID A5 "inbox" + string ID 1AD "SMS" , how can I make the string to be used by string2ID function???
(Please for S45i if you can)
Thanks

@lalo:
1/ Use this list : 138Fh, 00A5h, 01ADh, 7FFFh in your MessageBox stringlist parameter
2/ Convert x to the digit, and convert the result using string2ID using ID 138F
3/ Call the MessageBox with that string list.

@MASTER:
Ok, now I begin to undersand, but:
I don't know word2string () function, can you tell me (at least for SL45)?
And how to insert it in the beginning of my string?
Thanks

[ntcn]

Can I try to answer ?
Function 0CCCE9Ah (S45i, "DrawChargemonitorScreen") is used function 0FF41E8h ("Word_2_Str") which translates numbers to string . Parameters (for 0FF41E8h): r15 - number of symbols of a string (fill "0"), r14:r13 - destination address, r12 - number (word). If I am not mistaken

sl45 have a random number's generator ?

@teachers:
Thanks all, but still unable.
Could you tell me a patch where this "string with variable numbers" is used?
Morover, I don't need to put it into a MesgBox but to show it as a string.
So string content should be stored as text (no string IDs) in a (RAM?) location and pointed by r15:r14... possible?

Hello
I'm trying to create my own menu ItemHandler, but it doesn't work
Please correct me if i tell something wrong:
I got those from analizing Currency converter
0xE76450 - menuReserveTextSpace
0xE7620E - menuPrepare
0xE75884 - setMenuButtons
0xE7058E - setMenuEntry

Entry creation sequence:
menuReserveTextSpace
. give: R13:R12=entry_pointer R14=max_text_len
. get: R5:R4=place_for_text
menuPrepare
. give: R13:R12=entry_pointer
. get: R5:R4=some_saved_pointer
pGetStringByID
. give: R12=StringID R14:R13=place_for_text
setMenuButtons
. give: R13:R12=entry_pointer R15:R14=soft_buttons_pointer
setMenuEntry:
. give_stack: stack[3:2]=entry_number stack[1:0]=menu_text
. give_regs: R13:R12=entry_pointer R15:R14=some_saved_pointer
return

I save i registers, reserve only 16 bytes on stack and clean everything up before return.
It just hangs. Am i missing something, or i just messed up the handler code?

PS. I don't create new menu, only change ItemHandler in Currency converter to sequence i've described. Nothing more. I use #20h for max_text_len and "Setup" text from strings table for every entry.

About use my LPE patch, in address C42Ah stored offset and in C42C stored page of address were parameters placed for use parameters use this hint (see my example from RBL)

paramplace		EQU 0C42Ah
rxord			EQU 0
batVord			EQU 2

;---loading addres where place parameters--
extp	#pag(paramplace),#2
mov	r12,pof(paramplace)           ;in r12-offset
mov	r13,pof(paramplace)+2       ;in r13-page
;----loading parameters-----
extp	r13,#2
movb	rl6,[r12+#batVord]
movb	rl7,[r12+#batVord+1]
mov	r13,r6
mov	r12,r7

hi all!
I got an idea:

new patch, combined with patch "only show java in surf fun".
I was create new directory JAVA in disk A: on my mobile.
don't you may create a patch, which opens this directory throught this Java in menu (its a little fake, i know, but i think its a good idea )

This is a technical thread only, not a patch request one.
Please move your request from here to a proper place.

Hi all
I need to create a patch that is called as soon as possible. The problem is, I don't know which is the first routine that is executed. I have seen some code that sets CP, SP, STKOV, but I have no idea who calls this.
I also found some code that sets up the Interrupt table, but this is too late.
Regards

[Seklth]

Can I send inf to com port? Example for see this inf in terminal.

[fcotrina]

To send the value of rl3 to port serial 0 (COM1), do:
mov S0TBUF, rl3
bclr S0TIR
another_loop:
jnb S0TIR, another_loop

Be carefull not to send too much data. 1000 bytes is fine, but 1000*1000 is too much.

This is a tutorial how I solved my "problem" with the nice NSM_Selectable Patch:

because it´s useless (?)
