Problem In Reading A Text File

Suppose I am using this code to read a text file :

Code: 
DEFINE VARIABLE inputLine AS CHARACTER   NO-UNDO.
DEFINE STREAM sin.

input stream sin from T:/demo.txt.
repeat:
    import stream sin unformatted inputLine.
    ...
end.
input stream sin close.

Suppose the text file contains some text like :

A
B
C
D

with the last line not being terminated with a carriage return or line feed character.

What progress reads is

A
B
C
C

So the last line is not read correctly.
Is Progress aware of this issue ? I think this issue already exists for a long time.
Do you know of a workaround for this issue ?

Workaround: Add a carriage return or line feed to your file.
OUTPUT TO yourfile.txt APPEND.
PUT SKIP. or PUT CONTROL CHR(13) CHR(10).
OUTPUT CLOSE.
 
What Progress version? 10.2B or later you can use a LONGCHAR.
COPY-LOB from file MyFile to object MyLongCharVar.
Then you can parse the contents just as you would any character variable. So long as the file isn't massive it's often a lot better than streams as you aren't limited to a linear reading of the contents.
