Using the 'stack' function to combine an unknown number of matrices

[Scrat]

Hi there, I've written a program which reads in a data table from MS Access and displays these values in a matrix then does a whole load of stuff and produces a separate data table for each of the values which have been read in (using the Rkadapt function). These tables have been labelled Z[0, Z[1, Z[2 etc where the subscript number pertains to the position of the relevant value in the initial matrix. The problem i'm having is that I need the program to work for an unknown number of values read into the initial matrix, and therefore an unknown number of Z[n matrices. The whole program has been engineered to do this apart from the following command:

X:=stack(Z[0,Z[1,Z[2)

It seems to me that there is no way of modifying this code so that an unknown number of Z matrices could automatically be evaluated by the stack command, i.e. If 70 Z matrices were required because 70 values were read into the initial matrix, the above code would have to be changed MANUALLY to stack all 70 together. I've tried everything I can think of to make the program do this for me and nothing seems to work! If anyone could help with this I would be so grateful!

I don't understand. If you've got a program, why do you need to stack all the matrices at once? Why can't you loop on the stacking each matrix to the resultant from the previous stacking?
