Issue/Introduction

CA MII Programming states two samples about "Preventing Attribute Modification and PDS Directory Overwrites" ;

1. If you specify the name of a source library that has a record format of FB on a //SYSLMOD DD statement in a LINK step, then the record format of the library is changed to U, making the library unusable.
   
   
2. If you forget to specify a member name for the output from an assembly program. The data set organization of the PDS is changed from partitioned to sequential, making the PDS directory unusable.

Are there any other samples to see Preventing Attribute Modification and PDS Directory Overwrites by MII EDIF ?
