### 8.106 `FGET` — Read a single character in stream mode from stdin

Description:
  Read a single character in stream mode from stdin by bypassing normal formatted output. Stream I/O should not be mixed with normal record-oriented (formatted or unformatted) I/O on the same unit; the results are unpredictable.

  This intrinsic is provided in both subroutine and function forms; however, only one form can be used in any given program unit.

  Note that the `FGET` intrinsic is provided for backwards compatibility with `g77`. GNU Fortran provides the Fortran 2003 Stream facility. Programmers should consider the use of new stream IO feature in new code for future portability. See also Fortran 2003 status.

Standard:
  GNU extension
Class:
  Subroutine, function
Syntax:

  `CALL FGET(C [, STATUS])`
  `STATUS = FGET(C)`

Arguments:

  C | The type shall be `CHARACTER` and of default kind.
  STATUS | (Optional) status flag of type `INTEGER`. Returns 0 on success, -1 on end-of-file, and a system specific positive error code otherwise.

Example:

                PROGRAM test_fget
                  INTEGER, PARAMETER :: strlen = 100
                  INTEGER :: status, i = 1
                  CHARACTER(len=strlen) :: str = ""

                  WRITE (*,*) 'Enter text:'
                  DO
                    CALL fget(str(i:i), status)
                    if (status /= 0 .OR. i > strlen) exit
                    i = i + 1
                  END DO
                  WRITE (*,*) TRIM(str)
                END PROGRAM
