Visual Prolog 6.1 updates the format of PRJ6 file.

The following steps can be used to convert PRJ6 file from Visual Prolog 6.1 format to Visual Prolog 6.0 format.

1. Open it by some text editor and save as ANSI file.
2. Remove the line with the word "clauses".
3. Remove all dots in the end of each line.
4. Replace

tmpsl("status",s("prj_vers",0,6,r(6103.1),n(),
    st("v.6.1 build 6103"),0,0,0))

with

tmpsl("status",s("prj_vers",0,6,r(6001.7),n,
    st("v.6.0 build 6005"),0,0,0))
