[AWL] assign instruction = and index adressing

[rbrt95]

Hi everybody.
I got some problems about how to perform this task

Now, I got an FB where I have this code snippet that looks like:

L P##DBD_134
LAR 1
A [AR1, P#0.7]
= DIX 59.0

//where DBD_134 is a FB's STAT variable with absolute value 62.0

So basically it takes the 62.7 bit's value and store it in 59.0, which is a bit of the double word 56.

As you can imagine, this solution is not optimal because absolute adresses would change if I modify my FB's variables, and the instruction DIX59.0 would not be effective anymore.

How can I modify my code using pointer in order to the first bit of the third byte of the doubleword 56 (59.0)??

[L D[AR2,P#0.0]]

Can you post the FB code in a cut down library?


I would create a function that returns the absolute address of the STAT variables by passing it as an any pointer, if you change the offset within the instance DB the compiled code will point to the correct address.


How did the address 62.0 get into DBD_134?

[L D[AR2,P#0.0]]

e.g.

[L D[AR2,P#0.0]]

FC1 as follows:

[L D[AR2,P#0.0]]
