Hi Sandeep,
Is is possible to use 2 dimensional dynamic array ...
http://stackoverflow.com/questions/162753/using-length-with-multi-dimensiona
l-dynamic-arrays-in-delphi
You can have non-rectangular 2 dimensional dynamic array.
However, I don't think you can have non-rectangular 2 dimension array
constant so you may need to change the declaration to variable:
var 2DStrArr: array of array of string;
Cheers
Rodney

Hi Sandra
Perhaps if you share your existing algorithm we can help you faster.

Subject: [DUG] Make all possible unique combinations
I am looking for ideas to generate all possible combinations for the
following arrays. I don't want to use for.. loops as number of arrays
can change.
const
STGR : array[1..2] of string = ('A1', 'A2');
STG1 : array[1..4] of string = ('B1', 'B2', 'B3', 'B4');
STG2 : array[1..2] of string = ('C1', 'C2');
.
.
STGN : array[1..2] of string = ('N1', 'N2');
I have an algorithm to this but was wondering if there are other
simpler/better/quicker ways to do this.
Regards
Sandeep

Bet you dont remember the sex change operation either? :-)
Your problem however, needs more information.? If all you are doing is
generating the string but not changing it, then a function with two
arguments will do it.? If you are talking about storage then its another
story
