Re: [C400-L] QSYLOBJA Problem ...

[Dave McKenzie <davemck@xxxxxxxxxxxxx>]

Below is a version of the program that works.  The major changes I made are:

  1. You can't treat the list entries as an array because they're variable
length.
  2. For printf, the path name isn't a null-terminated string, so I built one
in allocated storage.

I'm sure there are simpler ways to do it, but this is what worked for me :-)
