              is enabled, the value returned will be "YES" if
              checking is not enabled, the value returned will
              be "NO".

Particulars

     This entry point allows you to "fetch" the current settings
     regarding the checking of components of a time string. This
     allows you to temporarily set the action to whatever is desired
     in a particular piece of code and then reset the action to
     the setting in effect prior to the routines activities.

Examples

     Suppose you'd like to write a routine that always applies
     component checking to the components of a time string.

     Use this entry point together with TPARCH and TCHECK to
     make use of the built-in SPICE capabilities

        get the current setting.

        CALL TCHCKD ( CURNT )
        CALL TPARCH ( 'YES' )

           perform some time
           parsing activities.

           check the components.

        CALL TCHECK ( TVEC, TYPE, MODS, MODIFY, OK, ERROR )

        Set the checking activity back to the value prior
        to the work done here.

        CALL TPARCH ( CURNT )

Restrictions

     None.
