Convert from mainframe to HP-UX

[Roy Taala]

Our project is planning to convert from mainframe to HP-UX. Since we're using
COBOL, I need to convert JCL scripts into Unix scripts. Do you have a tool that
automates this task?

in 1986 we converted a GIS application from IBM mainframe to VAX and then in
1992 converted it again to HP-UX.

If you want push-the-button conversion think again: JCL condition codes were
particularly obscure : skip this step if the following condition is not true!
what about iefbr14 , what about &&variable substitution? Even if some package
promised to produce equivalent unix scripts they would be guaranteed to
disappoint

instead start with converting your database or master file to HP-UX, what steps
are needed, can you preserve the data? can you use a commercial database? then
look at input/editing, are you going to keep batch processing?

there is the promise that cobol on IBM can be converted to cobol on HP-UX, what
part of the cobol stuff is so important? the more complex the logic the harder
it will be to preserve its meaning across a conversion, conversely the simpler
the logic the easier it is to ignore the existing cobol code and just develop a
new system
