Same.

The easy part was finding the hardware, configuring identical systems, 
and changing the date-era. Remember that we pre-dated TDD, so we pretty 
much re-designed entire testing suites! The most difficult work was with 
the oldest systems - for which there was no/little/worthless 
documentation, and usually no dev staff with 'memory'.

Then there were the faults in OpSys and systems programs on which we 
could supposedly rely - I still have a couple of certificates somewhere, 
for diagnosing faults which MSFT had not found... The difficulty of 
multi-layer fault-finding is an order of magnitude more difficult than 
Python debugging alone!

I'm told there are fewer and fewer COBOL programmers around, and those 
that survive can command higher rates as a consequence. Would going 
'back' to that be regarded as "up" skilling?

Does this imply that there might one day be a premium chargeable by 
Py2.n coders?
