Thanks Maarten and Moz for your help!!!
This is what I wrote last time:
-o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o-
I am still struggling with pointers and indexing them. The
current code I am trying to convert is contained in
some nested FOR loops:
===============================================================
A_RecordPtr: ^SomeRecordType;
i: uint32;
j: uint32;
pAuthDB: ^SomeOtherRecordType;
if
(A_RecordPtr[i].SomeBoolFunc(TransposeByteOrder(*(uint32*)&pAuthDB[j].DBID)))
===============================================================
How can I handle this without getting the dreaded
"Array Type Required" error?
-o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o-
However, it's not just a RECORD that I am trying to
operate on. Rather, there's a CLASS too. I should have
written:
-o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o--o-
I am still struggling with pointers to classes and records
(and how to index them). The current code I am trying to
convert is contained in some nested FOR loops:
===============================================================
A_ClassPtr: ^SomeClassType;
i: uint32;
j: uint32;
pAuthDB: ^SomeRecordType;
if
(A_ClassPtr[i].SomeBoolFunc(TransposeByteOrder(*(uint32*)&pAuthDB[j].DBID)))
===============================================================

I wish. With all the pointers, records, classes & indexes, the
levels of abstraction are almost too much for my brain to handle!

This makes perfect sense. I just wish I could get a handle on
all the indexing pointers to records/classes. Then I could
split off the other stuff into temporary variables, etc.

Which 'it'? Would that mean something like:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Type
SomeRecTypeAry: Array of SomeRecordType;
@SomeRecTypeAry := pAuthDB;
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Thanks again guys for your valuable advice. If you would
be so kind, please *point* me in the right direction
once more!
