name = %TTNAME
or
xcall TTNAME(name)
Return value
name
The name of the terminal at which the current process is running. (a)
Discussion
We recommend that you use terminal names for unique process distinctions rather than using the TNMBR environment variable.
On Unix, if the terminal name has the form below, TTNAME returns device_type/unit_number:
/dev/device_type/unit_number
On OpenVMS, if the program is running as a batch job, the TTNAME subroutine returns the “null” device specification: “_NLA0.”
