Format::fttp

Details

  • This message is generated when the second argument in Format is not a symbol.
  • The second argument in Format is expected to be a symbol that specifies a format type.
  • Off[message] switches off the message; On[message] switches it on. For example: Off[Format::fttp].

Examples

Basic Examples  (1)

The second argument in Format is a normal expression rather than a symbol:

Wolfram Language code: Format[FortranForm, test[p_]] := test[p, 0]

This example shows valid arguments in a formatting rule:

Wolfram Language code: Format[test[p_], FortranForm] := test[p, 0]
Wolfram Language code: FortranForm[test[7]]

Remove the formatting rule for test:

Wolfram Language code: Format[test[p_], FortranForm]=.
