OS/400 PASE application development tools and utilities

What debuggers are available in iSeries PASE?

The dbx utility is the debugger used for OS/400 PASE code.

Is there a way to use the source-level debugger on an OS/400 PASE program which has been spawn()'d from another?

Because compilation is done on AIX, it may be useful to mount the source code using NFS so that dbx can access it. You can connect to a particular process by using its procces id (pid).

Can executable program objects be stored in QOpenSys (in the integrated file system (IFS))?

All source code for OS/400 PASE is stored in stream files.

What editors are available in OS/400 PASE?

You can use one of the following:

  • The Source Entry Utility (SEU) allows you to edit file members in the QSYS.LIB file system.
  • The Edit Files (EDTF) CL command allows you to natively edit both stream files and QSYS.LIB file members.
  • A mapped network drive to OS/400 allows you to edit files using your favorite PC editor. You can map a drive using iSeries Support for Windows Network Neighborhood (iSeries Netserver).
  • Use one of the UNIX-like editors included in the iSeries Tools for Developers PRPQ.

Does OS/400 PASE support PERL programming?

Freeware is now available for download that will allow you to run Perl scripts on OS/400. For more information about how to download PERL, see PERL on iSeries.

Is there a version of zip available for OS/400?

There are several programs you can download or purchase to zip and unzip files in OS/400. They include:

  • GNU zip or gzip (Freeware). A version of the gzip GNU compression utility is available from IBM, along with other unsupported GNU utilities for OS/400. These utilities run from the Qshell Interpreter (qsh). You can see a list and download the GNU OS/400 utilities at GNU Utilities Download.
  • The UNIX qar utility is available in the iSeries Tools for Developers PRPQ.
  • Another version of gzip is available from the Free Software Foundation. This version is functionally the same as the IBM version, but is implemented as a program callable from the command line. You can download it at gzip for iSeries.
