RE: IBM pushing Java -- MIDRANGE-L


Hello Colin,

Wouldn't it depend on the quality of the current programmers?  Don't they 
understand the business and 
therefore have some value to the business regardless of the programming 
language?  Can't programmers (at least 
those with some talent) learn a new language fairly quickly?  They won't become 
experts overnight but they 
already know how to program -- they just need to learn a new syntax.  The trick 
with Java, Smalltalk, Eiffel, 
et al, is the OO component.  That takes some time to learn properly and the 
best way is to hire a mentor to 
assist with the design and help train your people in the process. However, if 
the programmer's are simply RPG 
hacks with no real interest in software (its just a job that pays them more 
than they can get eleswhere and 
puts a roof over their head, food on the table, and keeps the kids in school) 
then I think they should be 
replaced.

I can accept that a move from RPG to Java shouldn't be undertaken lightly 
(support reasons, etc) but that 
argument doesn't hold water for RPG IV.  The languages are similar enough that 
any competent RPG III/400 
programmer should be able to modify an RPG IV program with minimal pain.  They 
can get the reference manual 
and look up things they don't understand.  Initially they'll be a liitle slower 
but they should learn and get 
faster.

As Joel said earlier programmers are being required to be multi-lingual 
(program languages at least) and I too 
think that is A GOOD THING.

I keep seeing ads in the local paper for 'RPG programmer with 5 years 
experience, must know <insert business 
requirement du jour>, blah, blah, blah' when I think they should be asking for 
'Programmer with 5 years 
experience in <business requirement>.  RPG an advantage'.  Spot the difference? 
 Which add is likely to net 
the highest quality candidates?  Hmm.

Ahh, the more you know, the more the bastards ask you to do!

Regards,
Simon Coulter.
