Issue/Introduction

Using FileMaster Plus BROWSE of a VSAM dataset, why do I get a "IRX0555E IAMPRINT not allocated" error message?

Resolution

Check if your LPAR sets up VIO allocation as UNIT=VIO or UNIT=SYSDA to VIO?

If your LPAR is set up as UNIT=SYSDA to VIO then it must set up as UNIT=VIO.

This is requirement for FileMaster MVS.

The Install Guide states:

A unit type of VIO must be generated in the operating system.
