The pmode command talks directly to the plotting program chosen with the set plotting command. Any command usually typed to the plotting routine is now valid. Furthermore, all the current variables, constants and their string counterparts can be expanded in the plotting mode. The fitting macros and aliases are not recognized in this mode. The command fmode permits the user to return from the plotting mode as does ˆ D when typed interactively. If pmode is called with trailing arguments, the remainder of the line will be passed to the plotting program while remaining in fitting mode. It is not an error to call pmode from the plotting mode. An warning message will be given though.
If the plotting program is defined as a null string (set plotting "") then all command lines given in pmode will be ignored and warning messages will be given accordingly.
