Can't help with the rest but the DCL for WNT/95 is already available.
I found the following about 3 months ago.

XLNT (eXtended Language for WindowsNT) is a powerful scripting language 
and shell based on Digital's Command Language (DCL) found on OpenVMS systems.

Some of the features in XLNT include:

- Symbol Substitution (string and numeric)
- Nested Command Procedures
- built-in functions called Lexicals which provide various 
  services to the XLNT procedure writer
- Dynamic Error Trapping
- Modularized Command Procedure through the use of CALL and
  GOSUB statements
- WinNT command set including the use of XLNT features
- In-Stream Input Data for programs within a procedure
- Input / Output Redirection
- Built-in Simple Batch system
- Very powerful file and directory handling commands
- On-Line Help
and much more.... This is NOT a demo but rather a full
function system.

To obtain a copy of XLNT you may anonymous FTP into
"ftp.advsyscon.com" (please use your e-mail address as the
password).  The file 00README.TXT describes the various
platforms and variations (.ZIP and .EXE) of XLNT that are
available.
