| 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!

Why is it only "8 per Qualifier" ?  |

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. |
