The connect time estimate of 8.3 ms. is apparently 1/2 revolution of a 3380. Over 20 years ago (before 1989) was before the 3390 was first introduced, so a 3380's values would still be a correct value in whatever year that value was published. Whatever is reported by RMF will always be an integral multiple of 128 microseconds after rounding.

IOSRV=COUNT IOSRV=TIME was an option, a long time ago. I believe XA, but (as always) I could be wrong. And, back then, it was documented as 8.3ms. Or was it IOSRVC? - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
