REAL
- REAL {axis} This command extract the real part of the current the data set considered as complex. axis is not needed in 1D, can be F1, F2 or F12 in 2D, and can be F1, F2, F3, F12, F13, F23, or F123 in 3D On 2D and 3D you can choose on which axis the REAL operation will be taken. Data size can thus be reduced either by 2 , 4 or even 8. related contexts : $ITYPE_1D $ITYPE_2D $ITYPE_3D

REF
- This command will force a new computing of the display, as if a display command had been issued. This is useful for cleaning the spectrum after any command that draw on the spectrum, such as POINT, SHOWLINE, etc...
see also : CHECK3D DISP3D
REF3D
- This command will display a 3D view of the current 3D data-set, in the window previously opened with the DISP3D command. The parameters used for the display can be chosen with the DISP3D? and the CHECK3D commands.

REFMACRO
- When this context is set to 1 the program refreshes the on- screen display during macro execution, this permits to follow the data during the program execution, but slows down the macro execution. When equal to 0, the display is refreshed only at the end of the macro execution. Default value is 0.
