This chapter uses the following mnemonics to describe when a deviceparameter applies:
TRM Valid for terminals
S/S: Valid for sequential files when used with SPOOL or SUBMIT
SUB: Valid for sequential files when used with SUBMIT
SPL: Valid for sequential files when used with SPOOL
SD: Valid for sequential disk files independent of SPOOL or SUBMIT
MBX: Valid for mailboxes
NULL: Valid for null devices
SOC: Valid for socket devices
Many of the deviceparameter defaults shown are the basic VMS defaults, and are subject to modification before the invocation of GT.M. Modify terminal characteristics with the DCL SET TERMINAL command. Modify disk file characteristics with the DCL INITIALIZE, SET and MOUNT commands.
