First of all, you don't have to use cut to pass awk the 49th through 100th
columns of the data; awk can figure out what to use itself.  Second, awk is
capable of both splitting strings at specified columns (using substr) and of
keeping a running total.  Something like this:

awk 'BEGIN {
	column1 = column2 = column3 = column4 = column5 = 0;
}
{
	column1 += substr($0,49,10);
	column2 += substr($0,59,12);
	column3 += substr($0,71,10);
	column4 += substr($0,81,10);
	column5 += substr($0,91,10);
}
END {
	printf("%d %d %d %d %d\n", column1, column2, column3, column4, column5);
}'

P.S. By the way, both substr and the math capabilities of awk are among its
basic functions that are documented in the man page.  If you needed to ask on
the net about them, I think perhaps you need to do a little bit more
documentation reading.
