Multiple Operating Environments
System/36 Environment
Most System/36 applications can run on the iSeries server using the System/36 environment.
When running in the System/36 environment, all of the following options can be executed:
• IBM supplied procedures, as found on the System/36, such as BLDFILE, SAVE, and
RESTORE
• Operation control language (OCL) statements, such as // LOAD, // FILE, and // RUN
• Procedure control expressions (PCE), such as substitution expressions and IF
conditional expressions
• System/36 operator control commands, such as CHANGE, STATUS, and JOBQ
• System/36 RPG II and COBOL programs after they are compiled on the iSeries server
OS/400 supports a set of commands designed to migrate data between the System/36 and
the iSeries server or the iSeries server and the System/36. These commands save and
restore library source, procedure members, and data files between the two systems. A
separate licensed program, IBM AS/400 System/36 Migration Aid (5727-MG1), is available
on the System/36 to assist in migration from a System/36 to the System/36 environment on
an iSeries server.
System/38 Environment
The System/38 Environment provides for:
• Migration from System/38 systems
• Intermixing of System/38 and iSeries functions
• Maintenance of System/38 applications on the iSeries server
The System/38 Environment allows the execution of most programs written for a System/38
system. The same job can execute any combination of iSeries or System/38 programs. The
programmer menu on the iSeries supports source types to enable the identification of
System/38 syntax. The programmer can maintain either iSeries or System/38 programs
during the same job. Compilations of programs to be distributed to System/38s must be done
on a System/38. A separate licensed program, IBM AS/400 System/38 Migration Aid
(5714-MG1), is available on the System/38 to assist in migration from a System/38 to the
System/38 environment on an iSeries server.
Linux for iSeries
IBM is committed to supporting your choice of platform and operating systems – a
commitment now extended to include Linux, the open-source operating system. Linux
enables a new stream of e-business applications to complement the strengths of the iSeries
