Intellicorp tried to copy a sysout to the local Dlion disk with a COPYBYTES, eg. '
'
(COPYBYTES ''{0#1#}<NEWLISP>LISP.SYSOUT ''{DSK}LISP.SYSOUT).'
'
  The copybytes appeared to complete successfully, returning {DSK}LISP.SYSOUT;1. However, the local disk file gave its legnth as 1052296 bytes (2056 pages) whereas the file server had a length of 2709808 bytes (5293 pages).  '
'
As a work around I suggested that they create the file on the local disk first, then try the copybytes.  I haven''t heard whether this worked or not.'

'
um, maybe they tried COPYFILE rather than COPYBYTES? COPYBYTES only works on open files.'
'
Also, in interaction with Customers (even our friends at Intellicorp) you will do well to (a) include the name of the Customer (e.g., was it Yonke?) and (b) to cc 1100Support.pasa.'

I was talking to Marty Yonke.  He had opened the files.  He used COPYBYTES in preference to COPYFILE because when moving a large file to the file server earlier, COPYFILE would always timeout but COPYBYTES completed.'

there may have been a problem with opening the file in the wrong "mode" -- COPYFILE tries to preserve the "binary" mode, while if you just OPENFILE, you may get text mode. It doesn''t matter on IFSes, but it does matter on VAXen.'
