From: Keith Petersen <W8SDZ@Simtel20.ARPA> Bob, I can't answer your UC crck questions, Rick Conn would be best for that. However, I can offer an alternative means for checking files uploaded to a Unix system. Please get MICRO:<UNIX.CPM>CRCK2.C and try it. I find it quite useful and unambiguous. Ben Goldfarb did a super job of adding several new features which are detailed at the beginning of the CRCK2.C file. --Keith

I read your message again and edited your chart to show the proper
method for uploading the A.TXT and B.COM files. Remember that text
files stored under Unix do not have Carriage Returns, only Line Feeds
at the end of each line. Also the trailing control-Z's from CP/M text
files are NOT stored on Unix.
file upload ls -l uc crc's
name method char count -c (text) -C (binary)
A.TXT umodem -rt 390 C6700080 6C4AFFFFF
A.TXT uc -rt 390 C6700080 6C4AFFFFF
B.COM umodem -rb 1920 BC1400080 2540FFFFF
B.COM uc -rb 1920 BC1400080 2540FFFFF
The A.TXT crc from CRCK44 was 0C67, BYTEFREQ reported 512 characters
The B.COM crc from CRCK44 was 2540, BYTEFREQ reported 1920 characters
Note that the .COM file matches exactly on byte count. The .TXT
cannot, for the reasons outlined above.

From: Richard Conn <RCONN@simtel20.ARPA> The CRCs generated by UC match those generated by CRC (under ZCPR2 and ZCPR3), Keith's CRCK, and CRC on SIMTEL20. UC was written on UNIX System V to run on System V only (there are many differences between the System V and Berkeley UNIXes in their libraries), and I don't support it under anything other than System V. I question the output you have been receiving since the values are 8 digits long, where the values output by the -c or -C options of UC under System V are only four digits long. If you are running System V, clearly there is a problem with the UC installed there. If you are not running System V, the answer is clear. Keith's solution to use CRCK.C may be best since it is generic (I think). Rick
