VarBind --
For SNMP, a variable binding containing a name and a value.
The value portion is only meaningful in non-error response PDUs,
TrapPDUs, and SetRequestPDUs. It is meaningless in
Get and GetNext requests.
By convention, the value field for GetRequestPDUs
and GetNextRequestPDUs is always an instance
of the
ASN.1
data type NULL.
variable --
An object known to your shell that stores a particular
value. The value of a variable can be changed either from
inside a program or from the command line.
Each shell variable controls a particular aspect of your
working environment on the UNIX system. For example, the
variable PS1 stores your primary prompt string.
version --
A separate program product, based on an existing
one, but containing significant new code or new functions.

corresponding to the position of the viewfinder on the map.
