Hi David,

Great! I do not know at all about this OS: I wonder if the TPF implementation might target this platform already ?

I did it, so many thanks for appreciating :-)
If you need some additional info about it, Please ask.

Some info that you might find useful:
- TPF implementation works in native encoding. It converts network textual data from/to EBCDIC and uses EBCDIC internally.
- OS400 implementation works in ASCII. Additional (i.e.: non-standard) procedures support passing EBCDIC-encoded arguments (based on CCSIDs) between libcurl and the calling program. There are also internal "system-side" wrapper procedures to encode/decode data between the OS and libcurl.
- OS400 does not use autotools: they are not available outside PASE (AIX emulation). Instead, there are some specific qsh scripts (the IBM OS400 shell: very much weaker than bash) for compilation.
- I don't know if you have the QC3 crypto-library on zOS, but if so, you might also be interested in the libssh2 OS400 port I've done to enable scp/sftp protocols in OS400 libcurl. Pls check the libssh2 github repo... Yes I know: this not the most urgent ;-)

Cheers,
Patrick
