2D arrays in macro

[CARL Philippe (LBP)]

Dear all,

For playing with 2D arrays within macros it is usually recommended to use a
picture object of given width and height and given types.

But this little trick doesn’t apply in the case of the string type.

So is there another solution that could be used for 2D arrays of string
types besides the solution of having a linear array and dealing myself with
the 2 dimensions?

I thank you very much in advance for your lightings.

My best regards,

Philippe

Good day Philippe,

AFAIK not for the macro-language!

Would using tables help?

Regards

Herbie

Greetings,

There are two general schemes for dealing with multidimentional arrays in a 1D
array language:
a) Arrays of arrays - which require language support and extra overhead.
b) compute the 1D index from the dimensions and nD indices.

for(x=0; x<nx; x++)
   for(y=0; y<ny; y++)
      op(array[x+y*nx]);

Enjoy,

Fred
