To run it, compile any source file with switch -gnatd.E or --- -gnatd.F to get an ALI file file.ALI containing Alfa information. Then run --- this utility using: - --- Alfa_Test file.ali - --- This test will read the Alfa information from the ALI file, and use --- Get_Alfa to store this in binary form in the internal tables in Alfa. Then --- Put_Alfa is used to write the information from these tables back into text --- form. This output is compared with the original Alfa information in the ALI --- file and the two should be identical.
