/*              FOUND is .FALSE. */

/*     TABSYM, */

/* $ Detailed_Output */

/*     VALUES   is a subset of the values associated with the */
/*              symbol NAME. If the subset specified by BEGIN and */
/*              END exists, as many values as will fit in VALUES */
/*              are returned. If the subset does not exist, no */
/*              values are returned and FOUND is .FALSE. */

/*     FOUND    is .TRUE. if the subset of values is exists. */
/*              FOUND is .FALSE. if BEGIN < 1, BEGIN > END, END < 1, */
/*              END > the dimension of NAME, or NAME is not */
/*              in the symbol table. */

/* $ Parameters */

/*     None. */

/* $ Exceptions */

/*     1)  If there is an issue while reading the components of a */
/*         integer symbol table, an error is signaled by a routine in */
/*         the call tree of this routine. This normally indicates that */
/*         the integer symbol table is corrupted. */

/* $ Files */

/*     None. */

/* $ Particulars */

/*     FOUND will be false if the bounds of the subset specified by */
/*     BEGIN and END are out of range. Values of BEGIN and END which */
/*     specify bounds out of range are BEGIN < 1, BEGIN > END, */
/*     END < 1, or END > the dimension of NAME. FOUND is also false */
/*     if the symbol NAME is not in the symbol table. */

/* $ Examples */

/*     The contents of the symbol table are: */

/*        books   -->   5 */
/*                     10 */
/*        erasers -->   3 */
/*        pencils -->  12 */
/*                     18 */
/*                     24 */
/*                     30 */
/*        pens    -->  10 */
/*                     20 */
/*                     30 */

/*     Let the dimension of the array VALUES be 4. */

/*     The ouput values of VALUES and FOUND for the input values of */
/*     NAME, BEGIN, and END are contained in this table: */

/*        NAME         BEGIN    END     VALUES    FOUND */
/*        ----------   -----    ---    --------  ------- */
/*        pencils        2       3        18      .TRUE. */
/*                                        24 */

/*        pencils        1       4        12      .TRUE. */
/*                                        18 */
/*                                        24 */
/*                                        30 */

/*        desks          1       5               .FALSE. */

/*        books          2       1               .FALSE. */

/*        erasers        1      -2               .FALSE. */

/*        pens           1       5               .FALSE. */
/*        ---------------------------------------------- */

/*     Note that FOUND is .FALSE. for examples 3 through 6 because: */

/*     -  In the 3rd example, the symbol 'desks' is not in the */
/*        symbol table. */

/*     -  In the 4th example, BEGIN > END. */

/*     -  In the 5th example, END < 0. */

/*     -  In the 6th example, END is greater than the dimension of the */
/*        symbol 'pens'. */

/* $ Restrictions */

/*     1)  This subroutine does not check to see if the output array */
/*         VALUES is large enough to hold the selected set of values. */
/*         The caller must provide the required space. */
