Split Command

[Gregory Lypny]

Hi Everyone,

	I'm wondering whether the Split command can be used to create a 
numerical matrix from a tab-delimited field of numbers.  Example:  I 
have a field named "X" with N=1000 rows and K=10 columns for 10,000 
observations in total.  The data is tab-delimited, and each line ends 
with the Return character.  If I put field "X" into variable X and use

	split X by tab

I get a single vector instead of a matrix (which I expected because 
that's how the command is defined), but the dimension of the vector is 1 
x 9,001 rather than 1 x 10,000 because the first element of each row is 
skipped during the indexing process (999 rows), being delimited by 
Return rather than Tab.  I would like to be able to create an NxK matrix 
where each element is X[i,j]  (i=row and j=column) and be able to 
extract single-indexed Nx1 column vectors of the form X[j] --- X[1], 
X[2], ..., X[10] in my example here.  I know that I can build these 
easily using the repeat control structure, but I thought that a command 
like Split, or something similar, may already exist for this purpose.

	Regards,
