On hp-ux you can :-
split -2 filename
the above means split into 2 line chunks.
If you want to automate splitting a file in half you could use "wc -l filename" to determine how many lines in the source file, assign this to a variable and use the variable as the first parameter.
LINES=`wc -l filename`
VAR=`expr $LINES / 2`
split $VAR filename
