9.3.6 Operation of DB

DB prompts for input with a "db>" prompt. Typing a control-z at any point while entering a command will cause DB to immediately stop execution. The quit-program command will also cause DB to stop execution.

The rest of the command line after the "PMDF DB" will be scanned for DB commands separated by backslashes, \; i.e.,


$ PMDF DB command1\command2...
Each command specified will be executed from left to right as the command line is scanned. Placing commands on the invocation line is optional; if any are specified DB will terminate after the last one has been executed. If no commands appear DB will operate by prompting the user for commands.

When first invoked, DB will open your personal alias database file which is pointed at by the logical PMDF_PERSONAL_ALIAS_DATABASE. PMDF establishes this logical at system startup as a system-wide logical equated with SYS$LOGIN:ALIASES.DAT. Users wanting to store their alias files elsewhere must redefine this logical for their process. Note, however, that relocation of this file will interfere with the proper operation of PMDF's public alias features.

While entering DB commands to the "db>" prompt, the following command interaction features are available:
