handling the timing of MVS builds is to start the MVS build server only at night
and ensure that the MVS builders do not have short timeout values.
Writing an MVS build script
The best starting point for an MVS build script is an existing JCL fragment that is used
for transforming inputs into outputs. For example, suppose you want to create a builder
that compiles a C source file into an OBJECT file using IBM’s C/370 compiler. You
probably already have JCL that can be submitted as a batch job that does this.
When you create a build script for the MVS environment, you specify JCL statements
with additional TeamConnection syntax. This build script is parsed by the build server.
From the parsed results, TeamConnection allocates the specified ddnames and data
sets; it then determines and executes the programs dynamically. The MVS build server
uses the specialized TeamConnection syntax in the JCL to determine where to store the
parts involved in an MVS build.
All statements in the MVS build script except for comments and inline data stream must
start with two forward slashes (//).
Before you start writing your build script, refer to the manuals for the compiler, linker, or
other transformation program to determine the data set requirements. Pay particular
attention to the DCB attributes for LRECL, BLKSIZE, and RECFM.
Sample build scripts shipped with TeamConnection can be installed on MVS. Page
305 lists the sample build scripts. For instructions on installing these samples, refer to
the
Administrator’s Guide
If you are debugging a build script, these manuals are also the first place to look for
problems.
For more information about JCL syntax, refer to the
JCL User’s Guide

Reference
for your version of MVS. (These are listed in the bibliography at the back of
this book.)
The following sample MVS build scripts are shipped with TeamConnection:
fhbmasm.jcl
Calls the MVS assembler
fhbcobm.jcl
Calls the MVS COBOL compiler
fhbmpli.jcl
Calls the PL/1 MVS compiler
