EXEC PGM=BFXTR
This statement invokes the BFX module that establishes communication with the original, initiating
BFX procedure. Like BFXTI, this module need not be privileged and does not require PARM information.
However, if a single file is to be transferred, the single control statement may be supplied on
a PARM statement. If a PARM statement is supplied, the SYSIN dataset will be ignored.
SYSPRINT
This statement defines a file for the display of error and informational messages.
FILEIN or FILEOUT
These statements define the file to be used for sequential file input or output on the remote CPU. As
in BFXTI, only one of these DD statements will be used by the BFX program. FILEIN will only be
opened for input when a file is to be transferred from the responding CPU to the initiating CPU;
FILEOUT will only be opened for output when a file is to be transferred from the initiating CPU to
the responding CPU.
The user may change the DDNAMES of the input or output file through the use of the BFX control
parameters. This facility is particularly useful when several files are to be transferred with a single
execution of BFX.
SYSIN
This statement defines the BFX execution parameters to be used by the procedure on the responding
CPU. The format of these control statements is described below. It is the user’s responsibility to ensure
that the control statements passed to BFXTI and the statements passed to BFXTR are entirely
consistent with one another.
If a single file is to be transferred, the single control statement may be supplied as the PARM field (of
the EXEC statement) for the procedure using the BFXTI or BFXTR program. If this control statement
is supplied, the SYSIN field will be ignored.
BFX Execution Parameter Syntax and Placement
All input to BFX is free form input. The control statement (such as SEND) must precede all parameters but
may follow any number of leading blanks. Keyword parameters may be separated by commas or spaces.
The BFX parameter scanner treats equal signs, spaces, and commas as being equivalent delimiters between
words. For example, the following two sets of parameters are equivalent:
S T=XYZ,ID=ABC
S,T XYZ ID ABC
BFX Execution Parameters
The BFX execution parameters consist of three control statements, SEND, RECEIVE, and SUBMIT, and a
set of parameters. All three control statements use the same parameters, as shown in Figure 7 on page 14.
The SEND and RECEIVE control statements specify the direction of the file transfer. The SUBMIT control
statement specifies that a remote job shall be simply submitted on the remote host, then BFXTI will end activity.
