The selected variable is entered in the formula with [Insert] or [Back].
With [Cancel] you can exit the list without accepting a variable. The in-
dividual variables are described in Section 4.5.7. The character #
stands for a running number (usually from 1 to 9 or 10); this must be
entered manually. If you want to calculate EP1, for example, then EP is
inserted in the formula and you must enter the 1 in the formula editor.
If the method contains more than one data producing command before
the calculation then the command identification will be given before the
variables (e. g. 1M.TITER for the titrant titer used in the first titration).
Data concerning the titrations, measurements and calibrations have the
identification M for mode; evaluation data have the identification E for
evaluation; calculation data have the identification C for calculation. The
command identification (M, E, C) will be counted up separately for each
command type and does not necessarily correspond with the number
of the command line.
