&CELL: DEFINE
The variable should be a string of at most 10 characters, the first
of which should be alphabetic. Special characters may be used, unless
they coincide with any of the arithmetic operators. The total number
of variable names that can be stored is usually set to 100. If you
need more, you'll have to recompile the program with a suitable
value for MXVAR (Patchy sequence DIMENSIONS).
The variable name I is reserved, see ROWS for further details.
The value should be a valid algebraic expression. Details about
those can be found in the rubrique ALGEBRA of this help facility.
