[Info-vax] Potential loss of data problem in sftp client in TCP/IP Services ?

[JF Mezei]

At one point, VMS did add a "file size" hint for RFM=VAR files so that
unix like utilities could get a file size of the file without having to
use the C-RTL to count the bytes.

But we were warned that this file size hint was not 100% reliable.

Is it possible that the software uses this , but the guys who write it
weren't told the file size hint is not reliable ?
