ok. i've done it:
akw /text/ file.txt |nawk 'BEGIN {FS="|"}; {print $10"+"}' > file1.log
echo "p" >>file1.log
cat file1.log|dc > file2.log
grep -v "stack empty" file2.log
not the most elegant way but it works

sum(1B) SunOS/BSD Compatibility Package Commands sum(1B) NAME
sum - calculate a checksum for a file SYNOPSIS
/usr/ucb/sum file... DESCRIPTION
sum calculates and displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an algorithm which may yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has been transferred between machines with different-sized ints. USAGE
See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes). ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO
sum(1), wc(1), attributes(5), largefile(5) DIAGNOSTICS
Read error is indistinguishable from EOF on most devices; check the block count. NOTES
sum and /usr/bin/sum (see sum(1)) return different checksums. This utility is obsolete. SunOS 5.11 8 Nov 1995 sum(1B)
