Specifying source files

For non-z/OS® UNIX files, use this format of the SYSIN DD statement:

//SYSIN DD DSNAME=dsname,DISP=SHR

If you specify a PDS without a member name, all members of that PDS are compiled.

Note: If you specify a PDS as your primary input, you must specify either a PDS or a z/OS UNIX directory for your output files.

For z/OS UNIX files, use this format of the SYSIN DD statement:

//SYSIN DD PATH='pathname'

You can specify compilation for a single file or all source files in a z/OS UNIX directory, for example:

//SYSIN DD PATH='/u/david'
//* All files in the directory /u/david are compiled

Note: If you specify a z/OS UNIX directory as your primary input, you must specify a z/OS UNIX directory for your output files.

When you place your source code directly in the input stream, use the following form of the SYSIN DD statement:

//SYSIN DD DATA,DLM=

rather than:

//SYSIN DD *

When you use the DD * convention, the first XL C/C++ comment statement that starts in column 1 will terminate the input to the compiler. This is because /*, the beginning of a C or C++ comment, is also the default delimiter.

Note: To treat columns 73 through 80 as sequence numbers, use the SEQUENCE compiler option.

For more information about the DD * convention, refer to the publications that are listed in z/OS V2R2 Information Roadmap.
