genident
-- create an unused
identifiergenident(
)
creates an identifier not used
before in the current session.
genident()
genident(S)
S |
- | a character string |
an identifier.
genident(
)
creates an identifier with a name of the form Xi
,
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
of the form Si
, where i
is a positive
integer.genident
is a function of the system kernel.We 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
