Updates field attributes.

Syntax 

                                      {,newfieldname}
                                      {,enhancement }
     FIELDform {fieldtag    }         {,fieldtype   }
               {oldfieldname}         {,datatype    }
                                      {,initialvalue}

Parameters 

form             is the name of an existing form within the current forms
                 file.

fieldtag         tag assigned to the field in form screen design.

oldfieldname     name currently assigned to the field in the field menu.

newfieldname     replacement field name.

enhancement      replacement display enhancement code.

fieldtype        replacement field type.

datatype         replacement data type.

initialvalue     replacement initial value.  If $EMPTY is entered in the
                 first six positions of the parameter, initial value is
                 cleared.

Discussion 

The first two parameters of this command identify the field to be
updated.  The remaining parameters are the actual updates.  The field
menu update parameters (newfieldname...initialvalue) may be longer than
the corresponding number of character positions available on the Field
Menu in interactive FORMSPEC, in which case the input parameter is
truncated.

Example 

           FIELD PARTS a_b_ c A _ B_C_CODE,NONE,R,,D

Updates field menu selections for field a_b_c of form PARTS.
Specifically, the field name is set to A_B_C_ CODE, the field display
enhancement code is set to NONE (for no enhancements), the field type
value is set to R (for required), and the data type value is unchanged.
The initial value for the field is set to the character D.
