Re: COBOL – Still standing the test of time
#2Gonna take up IBM mainframe courses this year to see if I can learn more about mainframes. This architecture ia completely different from PCs and it's nice to learn new types of low level programming.

Master the Mainframe usually is around this time of the year, recommend it.

#4Article is 2012.
Edit: please add (2012) to the title.

Yeah exactly. I read sometime before they changed the name but the content sholdd be the same.
Re: COBOL – Still standing the test of time
#6I've always thought that the reason COBOL is still "popular" is that it became an entrenched technology many years ago, and the cost of replacement is high enough (and it works fine doing what it's doing) that no one wants to invest the time and money to replace it's usage.
This quote made me pause though, "COBOL remains the preferred choice for systems where application quality and operating cost remain important considerations". How much is COBOL being "chosen" vs. COBOL is basically required b/c of the existing codebase and systems that need to be integrated with?
The latter is my guess, and the choice seems to be really, "what's the best way to extend this existing system?" If that system is in Java, it's probably Java... C it's probably C... COBOL it's probably COBOL.

#7It's funny how it's presented as "standing the test of time". There is plenty of "old stuff" that still exists and those aren't tested by time either, it's just that there is not enough of an incentive or foresight to do something about it.
If general OOP-language software engineers had the same army of QA, PR, marketing and sales people that mainframes have you'd probably end up with the same thing. I'd say COBOLs continued existence isn't the main case, it's just a side-effect.

IBM and Unisys have their manuals online.
IBM Redbooks are quite good.

#9>> While many also debate the status of Java in relation to COBOL for business applications, COBOL remains the preferred choice for systems where application quality and operating cost remain important considerations, so often the case when addressing the ever-present issue of IT debt. When many businesses are facing mounting IT debt, the average cost per line of code for COBOL was projected to be £0.80 whereas the cost to address Java quality issues per line of code was £3.47, according to a recent IT study.
"That oil in the fryer at your local bowling alley that has gone rancid but they refuse to change it because the guy who knew how to drain the old oil quit - still standing the test of time"
While many also debate the status of new oil in relation to rancid oil for french fries, rancid oil remains the preferred choice for deep fryers where knowing how to change the oil and cost remain important considerations, so often the case when addressing the ever-present issue of stuff only Bill knew how to do. When many bowling alleys are facing mounting problems due to not making sure someone else could drain the oil besides 'their Bill', the average cost per gallon of oil for rancid oil already in the fryer was projected to be £0.00 whereas the cost to go to Costco and get 15 gallons of new oil was £8.73, according to Chelsea who is at Costco like every day.

Yeah I saw a full set of redbook manuals regarding low level sys prog and amazed by its quality.
