Software Reference Manual - NetEx

Preface
This manual describes the user interface to the Network Executive Software (“NESi”) H211 Bulk File Transfer
(BFX) utility for IBM z/OS systems. BFX is used in conjunction with NESi’s NETwork EXecutive
(NETEX®) family of software products for use on IP networks.
The first section of this manual, “Introduction” on page 1 is an introduction to BFX. It includes a description
of BFX, network configurations that can support BFX, and the three programs which compose BFX and how
they interact.
“JCL and Control Parameters for BFX” on page 11 presents user control statements and parameters. This
section also shows the JCL used when running BFX, including simple examples.
The third section, “Applications” on page 25, provides detailed examples using BFX.
The next section, “Installing BFX” on page 29, describes the installation of BFX. It includes defining default
values for control parameters described in the second section.
“Appendix A: User Modules” on page 59 describes how to write BFX user modules. The user modules are
called from user exits within BFX. These user exits were carefully placed within BFX to allow the user modules
to perform code conversion when not provided by NESi hardware or software (NESi provides for many
types of code conversion), to transfer non-sequential files, or to perform other special processing by outside
modules.
“Appendix B. BFX Internal Summary” on page 77 describes the BFX internal structure as it relates to writing
user block (or record) modules.
“Appendix C. BFX Error Messages” on page 91 contains BFX error messages.
“Appendix D. H211 User Abend Codes” on page 109 lists H211 user abend codes.
“Appendix E. BFX Condition Codes” on page 111 lists H211 condition codes.
BFX uses NETEX, but the reader does not need to understand NETEX to use the first four sections of this
manual and BFX. However, users creating their own user modules (as described in “Appendix A: User Modules”
on page 59) are assumed to be familiar with NETEX.
