[Info-vax] scp or sftp: file is "raw", needs to be parsed - possible to work around that?

[Gregory Reut]

Hi Richard,

Sorry for not mentioning the versions. Here's the scp version info I can get form the executable:
SYSTEM> scp -V
tcpip$ssh_scp2.exe:Scp2/SCP2.C:2002: CRTL version (SYS$SHARE:DECC$SHARE ident) is: V8.3-01

I have one spare disk which is just enough size to keep the iamge backup I need to transfer, so I've reinitialized it with ODS5 and now zipping the saveset and moving it there. 
Regarding file size hint - is it enough to use ANALYZE/RMS/UPDATE in the file, or there is anything else (or something different) should be done for it?

Thanks in advance!
Greg
