RTL - Sys - System
The Reset procedure fails on files that are
Read-only. This is easily worked around by adding the statement
FileMode := 0 just before calling Reset.

This is not a bug.
If FileMode <> 0, then the developer tells the RTL to open a file with *WRITE* access. That of course will fail for a read-only file.

Mr. A. has a point here.
I (admitting to be both submitter and checker of this report) have always assumed that Reset was used exclusively for read access. Which is 'more or less' true for text files but not for random access files.
I was going to bring up that the developer does not 'tell the RTL' anything (not explicitly) about how to open the file and that the RTL should assume 'read only' when Reset is used. But this is not correct.
Jordan, I think the status should be changed into 'Gotcha' (still assuming that it is not uncommon to think that Reset is generally used for read-only access) because this behaviour is not too well documented. If my assumption is not correct (majority vote) or when a remark about the file mode is added in the Help for Reset, the item can be dropped.

I agree. I'll update it now.

This drove me crazy.
My app worked just fine until I tried to run it from a CD where all of the files it uses are ReadOnly.
