Hi Experts:

    I am writing a Python script to add fields to a layer in file geodatabase.
    I want to add a field of GLOBALID type, but the Add Field geo-processing tool in ArcGIS 9.2 only support TEXT |FLOAT|DOUBLE|SHORT|LONG|DATE |BLOB|RASTER

    Is there any way for me to let the script add a GLOBALID field for me?
    Thank you.
