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...
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:
infilethe name of the file to input. When two angle brackets are used,
<<infile, the commands read from the input file will not be echoed as they are executed.
>outfilethe name of the log file. All commands you enter and information printed by DB will be written to the log file. To log only the commands you type, use the command
dcl-commandthe DCL command you want to execute.
