Yes L09777 sets the column quantity.

Yes two functions to get row and column, then do the table lookup.

You could add the function subs to your code sequence.

Sure, post up your analysis.

Have you spotted any code for the row count?

Have you spotted any code for the row count?
No I have not, but I would assume by the functions it calls it would be 8, but It is 16, So I am very confused about how it all works exactly. Looks like it Checks the table 3 times before outputting a value. But I am lost after adding all of the extra code it takes to actually perform a table lookup. Seems very overcomplicated but I am sure I am making it that way in my head..

Here is the complete Table lookup....I think?

Code: Select all

BOOSTEDEVERYTHING wrote: ↑2024 May 31, 10:20 No I have not, but I would assume by the functions it calls it would be 8, but It is 16, So I am very confused about how it all works exactly.
The two functions scale inputs to table dimensions as outputs. So an 8x8 table is a fair call.

Search for 15CDC does not find any hits in the code.
I've seen tables where two different subroutines access the same table but use different row counts, though that is not evident in this case.

Note swTb23EPPH @ 15c9c is similar.

The column scaler is unusual in that output increases above 0 for the last four rows after the input drops to 0.
The function lookup won't look in those lower 4 function rows as the input has hit the minimum input in the row above.

Code: Select all

   uuyFn.0x15d1c:
15d1c: ff,70              func  255, 112
15d1e: 50,60              func   80,  96
15d20: 28,40              func   40,  64
15d22: 00,00              func    0,   0
15d24: 00,10              func    0,  16
15d26: 00,10              func    0,  16
15d28: 00,10              func    0,  16
15d2a: 00,10              func    0,  16
The row scaler is even more unusual in that an input between 100 and 0 increases the column from 0 to 1.

Code: Select all

   uuyFn.0x15d2c:
15d2c: ff,70              func  255, 112
15d2e: c8,70              func  200, 112
15d30: ac,60              func  172,  96
15d32: 64,00              func  100,   0
15d34: 00,10              func    0,  16
15d36: 00,10              func    0,  16
15d38: 00,10              func    0,  16
15d3a: 00,10              func    0,  16
Looking at the functions alone I'd have gone with 8x8 until I found something to the contrary.
Looks like it Checks the table 3 times before outputting a value.
Interpolation. Rather than take the value at the intersection of the row and column, the four nearest cells are interpolated.
Here is the complete Table lookup....I think?
Looks ok.

EDIT: See bug details in post below.

Should have dawned on me earlier. You have found a bug.

The table name starts with sw, that is signed word.
The lookup sub Y16SW, that is byte input multiplied by 16, signed word output.

You see the problem...
The table is being treated as bytes.
It should be 2 bytes per word.
8 columns requires 16 bytes per row.
So 8 words per row (16bytes) x 8 rows, problem solved.

@TVRfan
V5.08 has this bug also.

So would there be a way for me to correct how it is being treated? Or would that have to be fixed in the actual SAD programming?

Not sure I understand this.

Really needs a programming fix on SAD.

You could bodge it with a structure command.

A value above 100 and a value below 100 lookup the same column location.

Is there a limit of how many characters you can put after a # before SAD starts reading the line in the DIR file again?
I got the above when I added some descriptions to some trouble codes in my DIR file. Was thinking maybe some are too long? They are on the same line as the #.

Are those character 256 or 257?
