How to get the name on currently opened dataset in REXX????

Hi All,

I am making a mainframe tool in REXX. This tool requires that i get the name of a opened dataset (PDS and member both). This tool will be executed inside of a dataset. Therefore i wanted to ask is there any way to get the name of the currently opened dataset into a rexx variable.

Does MVS stores the names of the dataset opened in side a system variable. For e.g SYSUID stores the current user logged in.

Since the SEARCH function appears to not be working:

3.3.21 DATASET--Query the Current and Original Data Set Names.

3.3.53 MEMBER--Query the Current Member Name.

Not to mention what else you might find in the REXX Reference manual.

A link for which I have put as a sticky in this very forum.

Take a look at (I think) LISTDSI with the FILE parameter.

Hermit ,

I do not see any thing wrong. Probably you are not executing it correctly. I tried it and it worked perfectly.

as it is a ISREDIT MACRO it will work only when you will run it while viewing or editing a dataset. you need to execute this like you issue a find or change command

I tried as shown below but still getting the same answer
have opened the dataset in edit mode.

GETDSN is the name of the REXX program

when you are EDITing/VIEWing a DS, you are within an ISPF application space. When you enter the name of a ISPF recognizable command/macro on the command line (or invoke thru a dedicated PF-Key) the command/macro will execute within the ISPF application space you are in (i.e. edit/view window).
an example: sub(mit) will act upon the member you are editing viewing. If you type TSO SUB, the command will be executed within a new application space - which is why you will be prompted for a DS/PDS(Mem) name.

so, when invoking an edit macro with <TSO #name>, even though you were in an EDIT/VIEW panel, the TSO part will invoke a new application and then invoke the command. Since you are in a new application - pure tso - and not an ISPF EDIT/VIEW 'sub-application', the macro attempts to run, accessing zvariables which are not set.

a few sites to visit Doug Nadel's website , Lionel Dyck's website and Schlabb's website each of whom has a collection of excellent articles and ready made REXX'S & CLISTS. Over the years, all have contributed to the MVS community. Also, each website has links to other websites which are of the same caliber. Schlabb's website has copies of out-of-print articles written by Jim Moore about ispf and tso, which I would suggest to anybody read.
