No, no I don't. The business users will have endured my standard lecture on sequencing and affinity so if they choose to ignore my sage advice then sympathetic as am I to them in their predicament I'm fine and thanks for taking an interest.
Likewise code pages and error handling. There's standard advice on the subject which these people ignore at their peril.
(The twin perils being explaining to our freakishly tall CTO what went wrong with their code and listening to me going "told you so")

Joking somewhat aside, files for all their obviously flaws and faults are a transport mechanism that's not going away any time soon. The best we can do as a group of professionals is try to enforce good practice and proper procedures. Clearly the very best we can do is to eliminate files, and I do aspire to that, but in the short to medium term they're like the common cold; you keep up with your vitamins but expect that you're going to catch one sooner or later.
Especially with mainframe. Once the CTG and zOS Connect roll out then there will be better options to move data to and from that platform but until then (and possibly after the current generation of coders have retired) we're wedded to DD cards.

Entails? Which of these issues are actually resolved by switching to a "transactionally safe" protocol? |

How about all of them if the setup is done correctly and something like MQ is used.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |
