/*     Variable  I/O  Description */
/*     --------  ---  -------------------------------------------------- */
/*      NUMLIN    I    Number of lines to be written to the file. */
/*      ARRAY     I    Array containing the lines to be written. */
/*      UNIT      I    Fortran unit number to use for output. */

/* $ Detailed_Input */


/*     NUMLIN   The number of text lines in ARRAY which are to be */
/*              written to UNIT. NUMLIN > 0. */

/*     ARRAY    The array which contains the text lines to be written to */
/*              UNIT. */

/*              The contents of this variable are not modified. */

/*     UNIT     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 the number of lines, NUMLIN, is not positive, the error */
/*          SPICE(INVALIDARGUMENT) will be signalled. */

/*     2)   If an error occurs while attempting to write to the text */
/*          file attached to UNIT, a routine called by this routine will */
/*          detect and signal the error. */

/* $ Files */

/*     See the description of UNIT above. */

/* $ Particulars */

/*     This routine writes an array of character strings to a specified */
/*     Fortran logical unit, writing each array element as a line of */
/*     output. */

/* $ Examples */

/*     The following example demonstrates the use of this routine, */
/*     displaying a short poem on the standard output device, typically a */
/*     terminal screen. */
