/*     TABVAL    I/O  Components of the symbol table. */

/*     The function returns the dimension of the symbol NAME. If NAME is */

/* $ Detailed_Input */

/*     NAME       is the name of the symbol whose dimension is to be */
/*                returned. If the symbol is not in the symbol table, the */
/*                function returns the value zero. This function is case */
/*                sensitive, NAME must match a symbol exactly. */

/*     TABSYM, */
/*     TABPTR, */
/*     TABVAL      are the components of a double precision symbol table. */
/*                 The table may or may not contain the symbol NAME. */

/* $ Detailed_Output */

/*     The function returns the dimension of the symbol NAME. The */
/*     dimension of a symbol is the number of values associated with */
/*     that symbol. If NAME is not in the symbol table, the function */
/*     returns the value zero. */

/* $ Examples */

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

/*     -------------------------------- */
