Restoration of a 90's Backend to Tcl and Protocol Engine started

I've started restoring a backend library to Tcl, called ATP (Advanced Token Parser), to be followed by a Protocol Engine, G3O (Genie III Object-Oriented - GENerIc protocol Engine).
I wrote them between 1992 and 1995 when I was working for BNR (Bell-Northern Research) and NORTEL (Northern Telecom) in Maidenhead, the U.K., where I was a test tool developer, producing PBX (DPNSS and DASS2) and PSTN Interactive Protocol Testers for SS7.
The early ATP prototype was hijacked as CLI by a project for BT DATAS (DMS 3 Analysis and Traffic Administration System), a downstream processor running on HP-UX with X-Motif GUI interfacing with the CLI (Command Line Processor).
CLI/ATP let you define the parameter definitions of commands, using parameter types and constructs based on ASN.1 and validate them before executing the commands. Simple to complex commands can be written with validation done before the callback is called which just does the work and does not need to worry about checking the input.
Let me know if anybody is interested, and I will post updates to tell you the progress of my project. I have to scan in the source code printouts (inches thick) and run them through an OCR program, then edit the code to remove errors and typos.
That's all for now. Time for dinner.

I'd certainly be interested in at least the ASN.1 components. Tcllib

does have a reasonable asn.1 module but not a complete implementation.

I've restored ATP and SLP (which incorporates getline.c). I haven't tried to build it on my Mac or a Linux VM. It's fresh off the scanner, OCR and manual editing/formatting. See if you can make it work on your computer(s). There's an example program in ATP which uses SLP. Bear in mind that this was an internal tool from the early 90's.

I managed to build ATP but it is broken when run because Tcl has deprecated some things and introduced others, like Tcl_Namespace. I'm currently working on redesigning the Atp2Tcl Adaptor.

I've fixed a few issues, tested ATP on Apple Mac and Ubuntu Linux, checked in my code to GitHub, and uploaded to Google Drive. Please have a go at using it. The demo program atpexmp.c has got lots of examples.
I've just got one request, in SLP, the command line history retrieval from UCB getline.c is not working with the up and down arrows on a Mac, but is working on Linux. Also, there is some local echo when you hit Enter which isn't there in Linux. If somebody can please take a look and fix it, I'd be most grateful. Thanks, Alwyn

I'm in the process of scanning in the G3O source code and converting to text using an OCR program.
G3O needs some work to modernise such as replacing Rogue Wave tools.h++
