I don't know why people ask such questions - why DSN length is limited to 44? Why SYSIN is called SYSIN? and...

Does the answer to such questions really make you to test the candidates?

Im also still wondering about that, why not 39 or 41 and why not SIN instead of SYSIN, Questions, questions, questions.

Hi Dick,

we know that but not the questioners.
I guess there are even people around having datasetnames of
44 characters without the periods.

As an interviewer, I've never asked such questions, though - aksed about what is DSN length limit, or may be limit of PARM on an EXEC statement - but not... why these limts? Does the answer to such questions really make you to test the candidates?

44 because that is all that was left out of the 80 after all the other HDR1 data fields was accounted for?

Maybe i missed a memo. . . As no one has asked, i've offered to be the target here. . .

Is the rule not still a maximum of 8 per qualifier with periods between up to the limit of 44 (less for gdgs)? So, 5 8's and 4 periods - ta daa 44


Have a great weekend!

Hello,

Because IBM (and others) really, really like powers of 2 . . . Notice how much exploits this (thingsd that are 4, 8, 16, 32, 64, 256, 1024, etc). It helps that these are good "boundaries" in binary as well. . .

As far as the 8's go, i suspect that this is because so many "things" have/had a limit of 8, so it was continued into "mvs" dataset names.
