[p4] Logging into P4V, then running P4 dos commands - single login possible?

[Geoff Rowland]

Currently, users are logging into P4V first.  We then have an external
application that runs some P4 DOS commands on that users machine,
however it doesn't seem to pick up the login information from P4V - it
always says "Perforce password (P4PASSWD) invalid or unset".  I don't
want to have to either hardcode the user+password in the script, or have
the user enter it twice (not really possible with the script we are
using).  The strange thing is, it seems if you run P4 DOS commands
first, you don't need to login to P4V a second time.  

 

Is there someway to get the login/ticket info from P4V in DOS?
