Thank you paul, that was helpful.

If possible, can you kindly get me in touch with them so I would not spend time on which is already been done?

If you look on llvm-dev for the discussion "[llvm-dev] Fixed Point Support in LLVM" you'll find them:
Leonard Chan leonardchan at google.com<mailto:leonardchan at google.com>
Bevin Hansson bevin.hansson at ericsson.com<mailto:bevin.hansson at ericsson.com>

Admittedly this looks like binary-scaled, not decimal-scaled (I've been following the discussion, but not closely), so it might not be directly helpful to you; I don't remember whether PL/I has binary-scaled types.  However, DWARF supports both binary and decimal scale factors, so the DIBuilder and LLVM debug-info support should permit both.

John Reagan john.reagan at vmssoftware.com<mailto:john.reagan at vmssoftware.com> will also be looking ahead to supporting these types when the OpenVMS project gets to the point of supporting their broad range of non-C/C++ compilers, which includes PL/I and COBOL.
