Mass conversion tools all share the same following features.

Once customized to local conversion requirements, they can automate the following tasks:

• Application inventory transfer and validation
  
• Program conversion: Assembler, COBOL, RPG II, Easytrieve, Dylacore, QUICKJOB, etc.
  
• Program compilation and link-edit (in mass)
  
• Identification and classification of data flows (i.e. files) according to data life cycles
  
• JCL conversion and generation of error free MVS JCL that meets customer standards
  
• Generation of file migration jobs that transfer and catalog disk and tape files

They are designed for - or compatible with - the mass conversion approach:

• A single execution can convert all programs and associated copybooks, or all JCL streams, or compile and linkedit all converted code
  
• Excellent performances keep mass conversion times very shorts
  
• CPU resources thrifty
  
• Generate summarized reports and detailed cross-references for accelerated result review
  
• Can be custom-modified to local conversion requirements using options, tables, commands, plug-ins, exit routines, macros, syntax tables, pre- and post-processors, etc.

They allow taking advantage of the mass conversion benefits:

• Prevents overlapping of VSE and z/0S operations
  
• Eliminate the need to track, freeze, or duplicate application maintenance
  
• Reduce operations and applications support disruption
  
• Make migration end-user transparent
  
• Deliver reliable quality
  
• Shorten the project timeframe
  
• Lower labor and cost
