Introduction to 64-bit FOCUS

Starting with release 7709, FOCUS on z/OS is delivered as a 64-bit product. Some of the requirements specific to this version are:

• All of the data sets delivered are in extended format, including, for example, FOCEXEC and MASTER.

  If you have your own versions of these data sets that you concatenate with the distributed libraries, you must either:

  • Recreate them as PDSE libraries, if you want to concatenate them in front of the distributed libraries.
  • Concatenate them following the distributed libraries.
• Compiled MODIFY procedures (FOCCOMP) are no longer supported. If you want to run a MODIFY procedure, you must have the MODIFY FOCEXEC available. The FOCUS RUN focexec command will now automatically be converted to EX focexec, so if you have a MODIFY FOCEXEC with the same name as the compiled MODIFY, it will be run.
• There is no longer the ability to create or use WINFORMS in conjunction with MAINTAIN procedures.
• You may need to recompile any user-written 3-GL subroutines you created, especially if they were created before FOCUS was required to be LE-compliant. Therefore, you must have the source code available.
