Procedure

     SYDELD ( Delete a symbol from a symbol table )

     SUBROUTINE SYDELD ( NAME, TABSYM, TABPTR, TABVAL )

Abstract

     Delete a symbol from a double precision symbol table. The symbol
     and its associated values are deleted.

Required_Reading

     SYMBOLS

Keywords

     SYMBOLS

Declarations

     IMPLICIT NONE

     INTEGER               LBCELL
     PARAMETER           ( LBCELL = -5 )

     CHARACTER*(*)         NAME
     CHARACTER*(*)         TABSYM     ( LBCELL:* )
     INTEGER               TABPTR     ( LBCELL:* )
     DOUBLE PRECISION      TABVAL     ( LBCELL:* )

Brief_I/O

     VARIABLE  I/O  DESCRIPTION
     --------  ---  --------------------------------------------------
     NAME       I   Name of the symbol to be deleted.
     TABSYM,
     TABPTR,
     TABVAL    I-O  Components of the symbol table.

Detailed_Input

     NAME     is the name of the symbol to be deleted from the symbol
              table.

              If the symbol does not exist, the symbol table remains
              unchanged. This subroutine is case sensitive, NAME must
              match the symbol exactly.

     TABSYM,
     TABPTR,
     TABVAL   are the components of a double precision symbol table.

              On input, the table may or may not contain the symbol
              NAME.

Detailed_Output

     TABSYM,
     TABPTR,
     TABVAL   are the components of a double precision symbol table.

              On output, the symbol table no longer contains the symbol
              NAME or its associated values. If NAME is not a symbol,
              the components of the symbol table remain unchanged.

Parameters

     None.

Exceptions

     None.

Files

     None.

Particulars

     None.

Examples

     In the following example the subroutine SYDELD is used to delete
     the symbol "MEAN_ANOM" and its values from the symbol table.

     The contents of the symbol table are:

        DELTA_T_A -->   32.184
        K         -->    1.657D-3
        MEAN_ANOM -->    6.239996D0
                         1.99096871D-7
        ORBIT_ECC -->    1.671D-2


     The call

        CALL SYDELC ( 'MEAN_ANOM', TABSYM, TABPTR, TABVAL )

     deletes the symbol "MEAN_ANOM" from the symbol table. The
     components of the symbol table on output are:

        DELTA_T_A -->   32.184
        K         -->    1.657D-3
        ORBIT_ECC -->    1.671D-2
