In EPICS 3.14.12 I am rather surprised to see the following warning generated by asSetFilename:
asSetFilename: Warning - relative paths won't usually work
Forgive me, but EPICS has no business making such judgements, and seeing this message flags up a very nasty future possibility that I'd like to forestall: no library ever has any business changing the working directory, and if anybody is thinking of adding such code, please don't!
I know this is only a warning: but it's not true, and it has no business being true. So long as you avoid obvious mistakes, relative paths will always work, so long as nobody calls chdir() without prior agreement from the application.
So, I suggest removing this warning from the code.
