10.2.1.2 Format Specifier

The format specifier indicates the format to use for data editing. It takes the following form:

[FMT=]format

format
Is one of the following:

• The statement label of a FORMAT statement

  The FORMAT statement must be in the same scoping unit as the data transfer statement.

• An asterisk (*), indicating list-directed formatting
  
  
• A scalar default integer variable that has been assigned the label of a FORMAT statement (through an ASSIGN statement)

  The FORMAT statement must be in the same scoping unit as the data transfer statement.

• A character expression (which can be an array or character constant) containing the run-time format

  A default character expression must evaluate to a valid format specification. If the expression is an array, it is treated as if all the elements of the array were specified in array element order and were concatenated.

• The name of a numeric array (or array element) containing the format

If the keyword FMT is omitted, the format specifier must be the second specifier in the control list; the io-unit specifier must be first.

If a format specifier appears in a control list, a namelist group specifier must not appear.
