split variable values into array

i have these values inside variable $blah

BUNGA TERATAI 3    5055     ITH      1     0     0     0     1     1
JADE TRADER    143W     ITH      4     0     0     0     4     4
MOL SPLENDOR   0307A     ITH      3     0     0     0     3     3

so how do I split them into array with the new line as the delimiter?

In which shell / programming language?

usr/bin/sh..I think it's bourne shell

Basic Bourne shell does not have an array variable type.

sorry, checked wrongly, it's korn shell
