Good morning.
Is it possible to change the generic ">_" prompt to an alternative, for example, "AR_Motor >_" or "DEC_Motor >_"? This is simply to avoid confusion about which session you're in when you have multiple sessions open (Teraterm).
Un saludo.
David.

I don't think that's possible.
If you have multiple sessions in Windows you could put them on different desktops and switch them using Ctrl-Win-arrow. With different desktop pictures/colours it would be easy to know where you are. :)

Put this in the library

Sub mm.prompt
Print "Myprompt >";
End Sub

Same here, I'm using OPTION PLATFORM to set where I am. OPTION LIST reveals it then.

Manual page 23 expands Peters answer.

Quote MM.PROMPT
If a subroutine with this name exists it will be automatically executed by MMBasic instead of displaying the command prompt. This can be used to display a custom prompt, set colours, define variables, etc all of which will be active at the command prompt.
Note that MMBasic will clear all variables and I/O pin settings when a program is run so anything set in this subroutine will only be valid for commands typed at the command prompt (i.e. in immediate mode).
As an example the following will display a custom prompt:
SUB MM.PROMPT
PRINT TIME$ "> ";
END SUB
Note that while constants can be defined, they will not be visible because a constant defined inside a subroutine is local to a subroutine. However, DIM will create variables that are global that that should be used instead.
