groupcode details
when we read information from the dwg file, a integer groupcode value is provided along with the information.
what is the meaning of this groupcode.
with regards

probably you mean groupcode-value pairs returned in resbuf for xdata a xrecord.
the meaning of group code is application specific. for example if some application stores its data as xdata attached to an entity only application itself knows how to interpret the data. the only thing which can be figured out without the application is data type (string, integer, double etc.)
see autocad's help:
dxf reference/advanced dxf issues/ extended data
