To generate MFSs you must first have added them to your project.
When you compile an IMS format, the system will generate .mid, .mod, .dif and .dof files, which are analogous to those created on a mainframe. However, in this system, the .dif and .dof file names do not generate hexadecimal file names. Instead, character-based names are generated. In addition, an extended file of suffix mfsx is generated – this is used by the IDE for controlling build dependencies.
The environment variable ES_MFSLIB is used to tell MFSGEN where to store the generated files. These files contain MFS source information that has been extracted and formatted into a smaller structure optimized for faster access during execution.
The .mid and .mod files are created in the current directory. You need to ensure that you specify the location of these files to the enterprise server that you will be using.
When you generate the first MFS you will see message DBDUT0U35U informing you that mfspef.dat does not exist. Enter C to specify that you want to create mfspef.dat (and the other files from the above list) and message DBDUT0U35U will not be displayed on subsequent MFS generations.
