Re: TSO REXX -- find absolute generation # from relative?

Al, 1) LOCATE is better than IGGCSI00. It handles accurate resolutions including wrap around for you. Both just use the catalog. Neither require allocation. 2) Dynamic allocation of the DSN=MY.GDG(rel) DISP=SHR with either BPXWDYN or SVC99 has the advantage of allowing you to specify

Re: TSO REXX -- find absolute generation # from relative?

Yes, even if there is a NEW Allocation on the GDG (creating a new G000V), as it holds an excuse enqueue on the entire GDG (though you would be able to allocate the DSN directly, but not relatively). That is why I started with the CSI (Catalog Search Interface). Possibly not 100%, but you

The few times I have had it wrap, you can check the highest record returned, it will be (if the -1 is 9998 you are there as well ) and then you can do a search from the bottom looking for the “Hole” in the numbering. I have had to do it a few times, but it is so infrequent (took our shop

That doesn't always work Al. When the GDG has wrapped the calculation gets messed up. Best to let Catalog Management determine the absolute name for a given relative. -- For IBM-MAIN subscribe / signoff / archive access

Re: TSO REXX -- find absolute generation # from relative?

Another option would be to use the Catalog Search Interface (CSI). I have an example in CBTTape.org File #960 (the DSNLIST REXX). If you are going for just the G00V000s, then the value of the just subtract the Relative DSN from the number of records returned take that

Re: TSO REXX -- find absolute generation # from relative?

Using LOCATE/CAMLST seems better than using SVC99/BPXWDYN to resolve relative->absolute since it doesn't require allocation of the data set, which might fail. One question that I have is (I assume) that LOCATE/CAMLST will always use the latest generations ("GDGNT"), so that if what you want is a

Re: TSO REXX -- find absolute generation # from relative?

Sam just updated my CBT file today (File 452 in the Updates). I had a tool called RXLOCATE that simply does a CAMLST LOCATE for a dsname in LOCDSN variable. /*rexx*/ LOCDSN = 'userid.GDG(-1)' */ address LINK "RXLOCATE" say LOCDSN 'RC=' rc

Re: TSO REXX -- find absolute generation # from relative?

Gil, Isn't just a BPXWDYN('ALLOC ... DISP(SHR) RTDSN(absdsn) RTDDN(ddn)') enough? I don't think that INFO is required, although it doesn't matter that much. BTW: "GDGNT" is probably an option that many will want. Kirk Wolf Dovetailed Technologies http://dovetail.com On Thu, Jul 25, 2019 at

Re: TSO REXX -- find absolute generation # from relative? [EXTERNAL]

Respectfully, I disagree, especially since you mention REXX. Using the WORD function, parsing is a snap. If word 1 is NONVSAM, word 3 is the dataset name. I.e., If Word(line_read,1) = 'NONVSAM' THEN gdgent = WORD(line_read,3) ; The last 'gdgent' filled in will be the last GDG. How does it
