0237b: d7,a0              jne   0231d            if (R52 != 5) goto 0231d;

First off 6E1A is between 0x0000 & 0x7FFF so it is a positive value.

Ok, I think I am finally starting to get the signed/unsigned numbers, sort of, lol. Still some confusion here, I will elaborate later when I can find a good example. I get the 0x0000-0x7fff is positive and anything over that is negative? How about a 2 digit number? say 0x6f? That may not even be a thing, and I am overthinking it again.

[/quote]Line 02373 sets R52 = 0, so we are starting at [0+6E1A], add the data bank prefix, = 0x16E1A.[/quote]
So if it is greater than or equal to 5 it clears R52 and sets back to zero?

[/quote]Line 0263C increments R52 by 1 on each loop.[/quote]
I think I understand this.

[/quote]Line 02371 skips Line 02373 while R52 = 0 through 4.[/quote]
This one confuses me a little, This line reads, to me, if R52 is greater than or equal to 5 it skips 02375, I was not understanding the {} on different lines until this explanation, Does that indicate that the code continues to the lines within the {} when the "if" is false? I think I am confusing myself even more, If I read this like above then the code would indicate if it is greater then or equal to 5 clear the register(or set it to 0) as per the command within the {}. If that (R52>=5) is false then perform the command on the same line?

[/quote]Line 02375 stores the current value of R52 so that it can be loaded back at Line 0231D.[/quote]
I understand this one as well.

[/quote]Line 0237B loops back to Line 0231D until R52 = 5, that is the loop stop. R52 = 0 through 4 will be processed.[/quote]
I think I read that the "!" means stop, is that correct? So I should read this line as " If R52 is equal to a 5, then stop the loop, if it is anything under 5, keep looping"?

You don't have to use minimum 3 letters for commands, So if you wish, you can make it more readable as you learn with -

Code: Select all

RBASE    52 00 0230E 02382                  #   # Temp Rbase for Sub 0230E

BYTE     16E14 16E23                             # Sub 0230E data

and commands are case insensitive and you can have multiple spaces etc for readability.

0x6f is positive.

if >= 5, reset to zero.

>= 5 it continues on L02373, not past it. The code between {} is executed.
Jump compare verses jump not compare does the opposite logic. Just follow the logic SAD displays.
When <5 it jumps to L02375.

!= means Not Equal 5 jump to 0231d for another loop.

So does “>=“ mean greater than or equal to, or am I reading that wrong?

RZASA Rbase E2 = 0x1180
Look up the opcode B3 and you should find the offset value F4 is signed.
You should know signed F4 is going to be negative.

Ues the TVRfan method for a negative;
0x1180+ (0x4f-0x100) = 0x1174 which matches the DIR entry for RZASA.

EQE3 Rbase D4 = 0x280
Look up the opcode B3 and you should find the offset value 4B is signed.
You should know signed 4B is going to be positive.

0x280 + 0x4B = 0x2CB which matches SAD output.

Are you able to resolve these now, or do you have specific question for each?

Looking at the EQE3 DIR you uploaded in the post above.

Code: Select all

SYM  00C6 "FLAG_REG57"                #UY
SYM  00C6 "FFG_LAMBSE2"               :B0 
SYM  00C6 "FFG_LAMBSE1"               :B1 
SYM  00C6 "FFG_VS"                    :B2 
SYM  00C6 "FFG_TP"                    :B3 
SYM  00C6 "FFG_PIP"                   :B4 
SYM  00C6 "FFG_MAF"                   :B5 
SYM  00C6 "FFG_ECT"                   :B6 
SYM  00C6 "FFG_ACT"                   :B7

Looking at the RZASA DIR I uploaded in an earlier post.

Code: Select all

SYM  00BA "FLAG_REG57"                #UY
SYM  00BA "FFG_LAMBSE2"               :B0 
SYM  00BA "FFG_LAMBSE1"               :B1 
SYM  00BA "FFG_VS"                    :B2 
SYM  00BA "FFG_TP"                    :B3 
SYM  00BA "FFG_PIP"                   :B4 
SYM  00BA "FFG_MAF"                   :B5 
SYM  00BA "FFG_ECT"                   :B6 
SYM  00BA "FFG_ACT"                   :B7

Looking at the EQE3 DIR command I posted previously.

Code: Select all

SYM    C6 "Flags_C6"                      # Y #
SYM    C6 "FFG_TP"                        :B3 #
SYM    C6 "FFG_PIP?"                      :B4 #
SYM    C6 "FFG_MAF?"                      :B5 #

I've tried to compare the use of FFG_LAMBSE2 in both EQE3 and RZASA, but found no good code matches for the use of that flag.

Did you simply copy all the BA flags from RZASA and re-address them as C6 in the EQE3 DIR you uploaded?

I had found a few of them that were the same and assumed they all should be the same. It was my mistake to assume that. I have been going through them and deleting the entries that do not align with both lst files since I uploaded them. I’m sorry. I should not have assumed. Wishful thinking I guess.
Also the explanation above for the temp registers and the other comparisons I posted above covers my questions about those. Thank you very much. I will finish going through what I have already added this week and post a revised dir file with my mistakes and assumptions edited out. Although, it did help me to see what it would look like if I got something wrong. But I still should not have assumed like that and have since seen the error in that. Again. I am sorry about that. I will not make the same mistake twice….hopefully. lol. At least not on purpose. I just happened to see that several of the comparisons I did find lined up exactly in the RZASA dir file and assumed that that may be standard practice for ford to just put those entries in the same line up in all code just in a different location. Again, I have since seen that it simply is not like that and I need to stick to how you showed me to compare on every entry. I am very sorry to have wasted your time with my assumptions. I should have asked about that or just not tried to shortcut the process.
