/*     CARD       I   Cardinality of (number of elements in) the cell. */
/*     CELL       O   The cell. */

/* $ Detailed_Input */

/*     CARD        is the cardinality of (number of elements in) the */
/*                 cell. */

/* $ Detailed_Output */

/*      CELL        is a cell. */


/*                 On output, the cardinality of the cell is CARD. */

/* $ Parameters */

/*      None. */

/* $ Particulars */

/*     The set cardinality (SCARDC, SCARDD, and SCARDI) and set size */
/*     (SSIZEC, SSIZED, and SSIZEI) routines are typically used to */
/*     initialize cells for subsequent use. Since all cell routines */
/*     expect to find the size and cardinality of a cell in place, */
/*     no cell can be used until both have been set. */

/*     The set cardinality routines are also used by library routines */
/*     which manipulate cells (including set and window routines) to */
/*     reset the cardinalities of cells as they gain or lose elements. */

/* $ Examples */

/*     In the example below, the size and cardinality of the character */
/*     cell FRED are set in the main module of the program FLNSTN. */
/*     Both are subsequently retrieved, and the cardinality changed, */
/*     in one of its subroutines, WILMA. */

/*           PROGRAM FLNSTN */

/*           CHARACTER*30     FRED ( LBCELL:100 ) */
/*            . */
/*            . */
/*           CALL SSIZEC ( 100, FRED ) */
/*            . */
/*            . */
/*           CALL WILMA ( FRED ) */
/*            . */
/*            . */
/*           STOP */
/*           END */
