But Duc, the beauty of the unsecured set is also what makes it tough
(nearly impossible) to cross reference. It could be set from a display, or
many displays, a piece of sequence logic or many pieces of sequence logic,
a program using FoxAPI, or AIMapi, a shell script using omset, and there
are probably other places as well.
It's easy enough to check sequence code for a particular C:B.P with several
tools that are available IF the C:B.P is constructed prior to run
time. (See Sascha's comments along this line)
It is also relatively easy to de-construct displays and search for an exact
C:B.P, but there could be substitution lists using text files, or partial
naming constructs in the display file. In each case additional (difficult)
checking is needed.
To the best of my knowledge there is no way to completely search for script
files and/or executables that set OM variables.
SO, should Foxboro provide a tool that manages to find 90% of the cases
where an unsecured write occurs, but cannot guarantee that it isn't used
somewhere else? I don't know, but I do know that it would take a really
huge effort to handle all of the cases could come up.
Regards,
David
