Question Title Did you know these two ways of finding out the working directory in use?

Let's see how. 

There are two library routines that allow to retrieve this information. 

1. C$CHDIR called using a blank data-item; example

     initialize curr-dir.|curr-dir pic x(256). 
     call  "C$CHDIR"  using  curr-dir. 
     display "Current directory: " curr-dir. 

2. C$GETENV called to inquire the user.dir Java property; example

     call "C$GETENV" using "user.dir" curr-dir. 
     display "Current directory: " curr-dir.
