Description from the author:
"The Rexx sockets API supplied with OS/2 TCP/IP is significantly different from the APIs supplied with VM/ESA and OS/390. REXXSOCKVM supplies an alternate API which is roughly source-compatible with the mainframe versions, eliminating one obstacle to porting Rexx programs.
Version 1.0 of the API should be considered an alpha. Code is complete except for the TRANSLATE and SELECT functions, except as noted below. However some functions and options have not been completely tested. I developed REXXSOCKVM to support another project and wanted to release the alpha version pending further work. Bug reports, especially if accompanied by a fix, are welcomed. Please report bugs to the author."
