where i is a positive integer. It is guaranteed that the
returned identifier has not been used before in the current
MuPAD session.S is given as
argument, then genident returns an identifier with a name

Example
1We create three new identifiers. The second identifier has a different prefix:
>> genident(), genident("Y"), genident()
X1, Y1, X2
In the next example, we assign a value to the identifier
X4. Then the next two calls to genident skip
the name X4:
>> X4 := 5: genident(), genident()
X3, X5
