Get the source code of a "compiled" REXX program

Sometimes it's neccessary to get the source code from a "compiled" REXX 
program. To do this, do the following: 

Issue 

 
  set rxtrace=on

in an OS/2 window and call the program from this window. Normally you 
should now have an interactive REXX interpreter session where you can 
execute the following code: 

 
  do i = 1 to sourceline(); call lineOut "d:\rexxsource.cmd", sourceLine( i ); end;
  exit

Now the file d:\rexxsource.cmd contains the source code of the REXX 
program (normally without any comments, of course).

programs, and especially Protect the source code of a REXX program if you 
want to prevent this for your REXX programs)
