/*
The IMAN ITK program contains the function 
USER_invoke_pdm_server(). This function is used to obtain the date 
of creation or modification of the specified part, given the part 
number as input. The value of the input_code argument controls 
whether the date of creation, or the date of modification is 
returned (input_code=1 returns creation date, input_code=2 returns 
modification date). The return code output_code indicates whether 
an error occurred - output_code=0 if successful, output_code=0 for 
failure.
