HP-IL checksums or not

RE: HP-IL checksums or not
Just for the record, I have decided not to store any checksum in the 16-bit ROM files.

According to the VERIFY command:

Code:

************************************************************************
* VERIFY - VERIFY A FILE                                               *
*          WILL ONLY READ THE FILE INTO DRIVER'S BUFFER, NOT TRANSMIT  *
*          THE DATA OUT, BECAUSE ANY PIL TRANSMIT ERROR SHOULD BE      *
*          DETECTED WHILE GENERATING THE FILE.  THE ONLY THING THAT    *
*          MIGHT GO WRONG IS THAT THE DRIVER MAY NOT RECORD ON THE     *
*          TAPE CORRECTLY.                                             *
************************************************************************

It verifies the file by requesting the device to read the file to see that there is data there, no data is actually transmitted.

With modern file systems we can take the storage safety for granted. Should CRCs be needed, I expect it will be applied in the application domain, mainly to pick and match pages for update.
