I have a rather dumb question, I recognize. But I've been struggling with it for the past day. There's a data set (CENTER.PARMLIB) in which TCPPROF member is contained. TSO MVSCUST opens this file for me. And I can also access it through DSLIST. Though I can't access it anywhere. Any other ISPF utilities just tells me either the ¡°Data set is not cataloged¡± or (if I specify the volume) ¡°Data set is not found¡±.
That's quite problematic because, on top of all that, system have been abending on me, crying 'bout lack of space in the dataset. But I can't edit CENTER.PARMLIB allocation because all the tools which seems to deal with that can't find the data set. Also, when using the ¡°ALLOC¡± command, it infers the dataset is prefixed the current login, SYSPROG1.
