/*     LINE       I   The line which is to be written to UNIT. */
/*     UNIT       I   The Fortran unit number to use for output. */

/* $ Detailed_Input */

/*     LINE     is the text line which is to be written to UNIT. */

/*              The value of this variable is not modified. */

/*     UNIT     is the Fortran unit number for the output. This may be */
/*              either the unit number for the terminal, or the unit */
/*              number of a previously opened text file. */

/* $ Detailed_Output */

/*     None. */

/* $ Parameters */

/*     None. */

/* $ Exceptions */

/*     1)  If an error occurs while attempting to write to the text */
/*         file attached to UNIT, the error SPICE(FILEWRITEFAILED) is */
/*         signaled. */

/* $ Files */

/*     None. */

/* $ Particulars */

/*     This routine will write a single text line to the device */
/*     specified by UNIT. UNIT may be the terminal, or it may be */
/*     a logical unit number obtained from a Fortran OPEN or INQUIRE */
/*     statement. When written, the line will have trailing spaces */
/*     removed. */

/* $ Examples */

/*     CALL WRITLN( LINE, UNIT ) */

/*     You have now written a line of text to unit UNIT. */

/*        longer defined. This only appears for platforms that */
/*        need it to differentiate between writing to a file and */
/*        the terminal screen (standard output), currently: VAX, */

/*        Moved the PC-LAHEY environment indicator from one environment */
/*        case to the other. The Lahey compiler on the PC does treat text */
/*        files and the standard output device differently. */

/*     Beta Version 3.0.1, 01-JAN-1995 (KRG) */

/*        Moved the description of the input variable UNIT from the $ */
/*        $Detailed_Output section of the header to the correct location */
/*        in the $Detailed_Input section of the header. */

/*     Beta Version 3.0.0, 11-JUL-1994 (HAN) */

/*        Edited master source file to correct the code for the */
/*        PC/Microsoft FORTRAN PowerStation environment. It should use */
/*        the same code as the VAX, not the PC/Lahey Fortran code. Also, */
/*        code was included for the DEC Alpha OpenVMS/DEC Fortran and */
/*        Sun Solaris/Sun Fortran environments. */

/*     Beta Version 2.0.0, 30-MAR-1994 (HAN) */

/*        Edited master source file to include new environments: */
/*        Silicon Graphics IRIX/Silicon Graphics Fortran, */
/*        DEC Alpha-OSF/1, and NeXT/Absoft Fortran. */
