The perĆpacket timeout, which can be set through LIST, ran out

before a reply was received. This means that the remote station

acknowledged (ACK) the command message but did not send

the reply in the allotted time. (cf. Error 92)

The remote station specified does not acknowledge (ACK) the

message. See discussion of Error 92 in ERROR WORD in User

Symbol undefined. This will occur if a symbol appears as the

previously.

System symbol must be a symbolic address. This error will occur

if a procedure name is used in place of a symbolic address in an

assignment statement or if the system symbol referenced in an

assignment doesn't exist.
