The Unix, Atari, VMS, MS-DOS and OS/2 versions of GNUPLOT support command line-editing. Also, a history mechanism allows previous commands to be edited, and re-executed. After the command line has been edited, a newline or carriage return will enter the entire line regardless of where the cursor is positioned.
The editing commands are as follows:
On the IBM PC the use of a TSR program such as DOSEDIT or CED may be desired for line editing. For such a case GNUPLOT may be compiled with no line editing capability (default makefile setup). Set READLINE in the makefile and add readline.obj to the link file if GNUPLOT line editing is to be used for the IBM PC. The following arrow keys may be used on the IBM PC and Atari versions if readline is used:
The Atari version of readline defines some additional key aliases:
(The readline function in gnuplot is not the same as the readline used
in GNU BASH and GNU EMACS. It is somewhat compatible however.)
