    Hi John,

    I am unable to post the original files, so I created a test project consisting of an 8-bit counter.
    There are 3 files in the zip.

    testv16.jam, Compiled in 16.1, JAM size is 73 KB

    testv20.jam, Compiled in 20.1, JAM size is 185 KB

    testv20_v16.jam, Taking the POF from 20.1 and using the 16.1 programmer to create the JAM, JAM size is 73 KB.

    Thanks.
