  When you begin to work with i5/OS PASE, the points listed in this topic might be helpful to you.
• Prepare programs to run in i5/OS PASE
  The steps you need to take to prepare AIX programs that run effectively on i5/OS vary with the nature of your program and your actual needs for i5/OS system-unique interfaces and functions.
• Use i5/OS PASE programs in the i5/OS environment
  Your i5/OS PASE program can call other i5/OS programs running in your job, and other i5/OS programs can call procedures in your i5/OS PASE program.
• Debug your i5/OS PASE programs
  The i5/OS PASE runtime environment provides library support for the syslog() runtime function, and a syslogd binary (for more sophisticated message routing). In addition, you can use existing facilities in i5/OS, such as job logs for diagnostic messages and sending severe messages to the i5/OS system operator message queue, QSYSOPR.
• Optimize performance
  To achieve the best performance, be sure to store your application binaries in the local stream file system.
