MacMidrangeThe Apple® Mac OS Solution for IBM® AS/400® Client Access Connectivity

Now you can access the AS/400 from your Macintosh with a family of product solutions in a single integrated package. Developed around the same core code as IBM’s Client Access for Windows and OS/2, the MacMidrange Client from NLynx Systems is true AS/400 Client Access software for Apples’s Mac OS. MacMidrange Client allows you to connect a Macintosh or clone to an AS/400 and perform tasks such as sharing files, terminal and printer emulation, and to view your files in graphical format. MacMidrange Client also supports Open Database Connectivity (ODBC) for database serving.



  • Flexible terminal emulation for your AS/400. MacMidrange Client gives you the flexibility to meet special user and keyboard function needs. MacMidrange Client emulation incorporates easy-to-use functions such as cut and paste, cut and append, and hot spots. The auto-key feature permits automatic recording and playback of frequently used key combinations. Online keyboard remapping allows the simple remapping of keyboard functions. MacMidrange Client also allows on-screen, tear-off keypads for convenient placement on the desktop. Color attributes may also be modified, and 132-column mode is supported.
  • Integrated File System Support. Manipulate files quickly and easily with MacMidrange Client. Mount an AS/400 volume like any other remote Macintosh volume, then create, delete, and copy files and entire folders to and from the AS/400 with a simple click and drag of your mouse. QDLS (Office Vision) files are automatically translated to your favorite Macintosh data format for use on your Macintosh.
  • More Ways to Use Data. MacMidrange Client lets you make more effective use of your data. Now you can arrange and organize your databases in the ways best suited to meet your needs. The MacMidrange Client Drop Table allows you to quickly create and retrieve databases on the AS/400. Column headings, cell formatting, and delimiters can be automatically determined from the text file or can be user defined.
