DESCRIPTION ^

IDX_CT  Defines constants for named column indices to changes table

   [CT_LABEL, CT_PROB, CT_TABLE, CT_TBUS, CT_TGEN, CT_TBRCH, CT_TAREABUS, ...
   CT_TAREAGEN, CT_TAREABRCH, CT_ROW, CT_COL, CT_CHGTYPE, CT_REP, ...
   CT_REL, CT_ADD, CT_NEWVAL, CT_TLOAD, CT_TAREALOAD, CT_LOAD_ALL_PQ, ...
   CT_LOAD_FIX_PQ, CT_LOAD_DIS_PQ, CT_LOAD_ALL_P, CT_LOAD_FIX_P, ...
   CT_LOAD_DIS_P, CT_TGENCOST, CT_TAREAGENCOST, CT_MODCOST_F, ...
   CT_MODCOST_X] = idx_ct;

 CT_LABEL: column of changes table where the change set label is stored

 CT_PROB:  column of changes table where the probability of the
           change set is stored

 CT_TABLE: column of the changes table where the type of system data 
           table to be modified is stored;
           type CT_TBUS indicates bus table
           type CT_TGEN indicates gen table
           type CT_TBRCH indicates branch table
           type CT_TLOAD indicates a load modification (bus and/or gen tables)
           type CT_TAREABUS indicates area-wide change in bus table
           type CT_TAREAGEN indicates area-wide change in generator table
           type CT_TAREABRCH indicates area-wide change in branch table
           type CT_TAREALOAD indicates area-wide change in load
                             (bus and/or gen tables)

 CT_ROW:   column of changes table where the row number in the data
           table to be modified is stored. A value of "0" in this column
           has the special meaning "apply to all rows".  For an area-wide
           type of change, the area number is stored here instead.

 CT_COL:   column of changes table where the number of the column in
           the data table to be modified is stored
           For CT_TLOAD and CT_TAREALOAD, the value entered in this column
           is one of the following codes (or its negative), rather than
           a column index:
           type CT_LOAD_ALL_PQ modify all loads, real & reactive
           type CT_LOAD_FIX_PQ modify only fixed loads, real & reactive
           type CT_LOAD_DIS_PQ modify only dispatchable loads, real & reactive
           type CT_LOAD_ALL_P modify all loads, real only
           type CT_LOAD_FIX_P modify only fixed loads, real only
           type CT_LOAD_DIS_P modify only dispatchable loads, real only
           If the negative of one of these codes is used, then any affected
           dispatchable loads will have their costs scaled as well.
           For CT_TGENCOST and CT_TAREAGENCOST, in addition to an actual
           column index, this value can also take one of the following
           codes to indicate a scaling (CT_REL change type) or shifting
           (CT_ADD change type) of the specified cost functions:
           type CT_MODCOST_F scales or shifts the cost function vertically
           type CT_MODCOST_X scales or shifts the cost function horizontally
           See also MODCOST.

 CT_CHGTYPE: column of changes table where the type of change to
           be made is stored:
           type CT_REP replaces old value by value in CT_NEWVAL column
           type CT_REL multiplies old value by factor in CT_NEWVAL column
           type CT_ADD adds value in CT_NEWVAL column to old value
