to re-create this problem:
create a file AAA.JUN with one line, three characters AAA
create a file BBB.JUN with one line, three characters BBB
Then, in a DOS window: COPY *.JUN ALL.ALL
then read the ALL.ALL file using the LINEIN function.
(I was using Regina 3.5, Windows/XP Pro)
It will read three records:
where the x is a right arrow ('1a'x) which is the EOF character.
This also fails on the older Regina versions as well.
This type of end-of-file should be recognized by Regina.
