The SofTouch REXX SuperSet/2 Extensions

• REXX SuperSet/2 has a strong orientation on communications activities
• The REXX SuperSet/2 overlaps both REXXUtil and REXXLib
• Each function category consists of a separate DLL, allowing registration of only those functions needed
• REXX SuperSet/2 delivers 370 functions in eight classes:

  • Communications Manager/2 CPIC Functions
    • These functions are useful to those who are programming in a Communications Manager/2-supported environment (generally either a 3270 or 5250 host-connected terminal environment)
    • Use requires an understanding of the "C" language CPIC APIs.

  • EHLLAPI Interface Functions
    • These functions provide an interface to Communications Manager emulator sessions.
    • Supports access to all EHLLAPI services excepting asynchronous services.

  • "Host" Functions
    • These four functions provide services that are available on most MVS and VM/CMS operating systems.
    • The supporting DLL must be registered with a "subcommand" name such as "TSO"
    • In general, the entire host command string should be assigned to a variable; then, invoke the command by "addressing" the "subcommand" environment with the variable

  • LAN Server Interface Functions
    • Provides an interface to the IBM LAN Server and Warp Server APIs.
    • Many of these functions may also be usable for IBM Peer Services.

  • NetBIOS Interface Functions
    • Provides a single function name to be use with any of eighteen parameters to perform NetBIOS services.

  • TCP/IP Interface Functions
    Provides an interface to the TCP/IP Sockets and FTP APIs.

  • User Profile Management Functions
    • Provides an interface to User Profile Management services.
    • Supports administration activities in a LAN Server environment.

  • General OS/2 Utility Functions
    Provides an interface to many low-level and high-level services for the OS/2 environment.
