NetRexx Examples (Running ooRexx Scripts from NetRexx)
Hint: if you wish to look at the ooRexx code with syntax highlighting, then you can
use the free and open-source editor "[g]vim"
, which is available for practically
all platforms and can be downloaded from its homepage at
http://www.vim.org/.
- . <directory> (List of this directory)
- Display all of this directory's files and directories.
- .. <directory> (List of parent directory)
- Display all of the parent directory's files and directories.
- handlers <directory>
- Root of Rexx handler samples (cf. "rexxapi.pdf", section
1.16. Command Handler Interface).
- nrxRunRexx_01.nrx
- Defines and runs a Rexx program.
The compiled Java class is stored in "nrxRunRexx_01.class".
[Java version: JavaRunRexx_01.java.]
- nrxRunRexx_02.nrx
- Preloads the Rexx interpreter, defines and runs a Rexx program.
The compiled Java class is stored in "nrxRunRexx_02.class".
[Java version: JavaRunRexx_02.java.]
- nrxRunRexx_03.nrx
- Defines and runs a Rexx program, that returns an ooRexx directory, which then is
used from NetRexx (Java).
The compiled Java class is stored in "nrxRunRexx_03.class".
[Java version: JavaRunRexx_03.java.]
- nrxRunRexx_04.nrx
- Defines and runs a Rexx program, that contains a syntax error, which then is
intercepted and inspected by NetRexx (Java).
The compiled Java class is stored in "nrxRunRexx_04.class".
[Java version: JavaRunRexx_04.java.]
- nrxRunRexx_05.nrx
- Demonstrate how to setup a
.host
directory in Rexx from NetRexx
(Java), which then receives Java objects for use in Rexx programs; in addition
a value is saved in .host
by Rexx under the index REXX.HEY
that upon return is fetched from NetRexx (Java).
[Java version: JavaRunRexx_05.java.]
- nrxRunRexx_06.nrx
- Demonstrate how to use the context of a Rexx routine (i.e. all public
routines and public classes available to it) for another Rexx routine.
The first routine requires BSF.CLS
which adds
public routines and public classes which then are made available to Rexx
routines that get created and executed later via NetRexx (Java). In addition the
ooRexx standard streams get redirected to the Java standard streams by
calling the public routine bsf.redirectTo
.
Then another Rexx routines gets defined to use the first package, and in addition
defines a public routine named test
.
Finally, the last Rexx routine demonstrates getting access to the package
of the second routine which makes its public routine named test
accessible. In addition the last routine is called twice, once without
NetRexx (Java) supplied arguments, once with NetRexx (Java) supplied arguments.
[Java version: JavaRunRexx_06.java.]
- rgf_01_runRexx.nrx
- Shows the output of
parse source
and parse version
from
Rexx and NetRexx.
The compiled Java class is stored in "rgf_01_runRexx.class".
- rgf_02_runRexxArg.nrx
- Supplying an argument from NetRexx to a Rexx program.
The compiled Java class is stored in "rgf_02_runRexxArg.class".
- rgf_03_runRexxGetReturnValue.nrx
- Supplying an argument from NetRexx to a Rexx program, retrieving a Rexx return
value in NetRexx.
The compiled Java class is stored in "rgf_03_runRexxGetReturnValue.class".
- rgf_04_runRexxGetReturnValue.nrx
- NetRexx uses Rexx to query the
PATH
environment variable.
The compiled Java class is stored in "rgf_04_runRexxGetReturnValue.class".
- rgf_05_runRexxEnvironment.nrx
- NetRexx uses Rexx to query and set an environment variable called
RexxLA
.
The compiled Java class is stored in "rgf_05_runRexxEnvironment.class".
- javax.script (a.k.a. "jsr-223": "Java Specification Request 223", the expert group that defined the Java scripting framework)
- Demonstrates how to take advantage of the Java scripting framework
(cf. Java package e.g. at "javax.script")
introduced with Java 6.
