The ITI File-System Interface
Applications can be NonStop software (such as PATHWAY or TACL) or user generated
software.
The remote terminal can be 6510, 6520, 653x, a PC6530, or an ASCII character-mode
terminal. Terminals can be accessed in page or conversation mode. An ASCII terminal
can be accessed only in conversation mode. Terminal and terminal-PAD emulators that
emulate these terminals are also supported.
The ITI File-System Interface
Your application interfaces to the X25AM ITI procedures by using a subset of the
Guardian file-system procedures. This group of file-system procedures is called the ITI
file-system interface.
File-System Procedures Supported by ITI
ITI supports only the file-system procedures that are necessary to perform ITI tasks.
Table 2-1
lists the supported procedures for G-series RVUs. For D-series procedures,
see Appendix C, D-Series Supplement for X25AM
.
