Prompt

A prompt is a character or set of characters used in a command line interface to prompt user for action, i.e. signify readiness to accept the user's commands. The default DCL prompt is a dollar sign ($), the extended line prompt is _$. OpenVMS utilities such as AUTHORIZE or SYSGEN have their own prompts.

In OpenVMS, the prompt is an attribute of a process and can be changed with the SET PROMPT command.

The current process's prompt can be obtained using the "PROMPT" item with the F$ENVIRONMENT() lexical function.
