Read_array

Function: read_array (<S>, <A>)

array (A, 2, 3);
read_array (file_search ("array.data"), A, comma);
arraylist (A);
A;
read_hashed_array (file_search ("array.data"), B, comma);
arraylist (B);
B[Schmidt];

Function: read_array (<S>, <A>, <separator_flag>) Reads the source <S> into the array <A>, until <A> is full or the source is exhausted. Input data are read into the array in row-major order; the input need not conform to the dimensions of <A>.

The source <S> may be a file name or a stream.

The recognized values of <separator_flag> are comma, pipe, semicolon, and space. If <separator_flag> is not specified, the file is assumed space-delimited.
