I cannot reproduce your error. The script you posted is virtually identical to the script I posted bar subtle spacing within the "bc" command.

All I can guess is that the file p3data is in some way corrupt or that the data or script have been edited with a Microsoft editor and contain funny characters.

If you get an error message, please post the error message verbatim and also try running the script with "set -x" on the second line (execute trace) to try to find which line is producing the errror.

Well I can't thank you enough methyl and all who pitched in to help with this. It really helped me to grasp some more knowledge of UNIX and I appreciate your time in helping me to achieve this knowledge. Upon looking at the output file the F2C and C2F both work, I do get a syntax error with C2F but it doesn't seem to affect the output file. Well, on to the next one.

A blank line in the file will do this. The error is from bc. If $ct has no value, ( * 9) is not ok, but ( -32) is. You can check for blanks [[ $ct ]] || continue

Many thanks to neutronscott. I can now reproduce the error by inserting a blank line into p3data !
