Test if a file exist

April 16, 2007, 10:45 AM

Sorry for my english, it is not very good.

I try to test if a file exist in the way of conditionning my prodecure (focus format : UFILE for example). I don't find the solution in my books.

Can you help please?

Use the STATE command, then check &RETCODE. It will be 0 if the file exists or -1 if it does not exist.

STATE pathname/car.foc
-RUN
-IF &RETCODE NE -1 THEN GOTO SKIP_CREATE;
-*
CREATE FILE CAR
-RUN
-SKIP_CREATE

Interesting.

I couldn't find the STATE command in my WF 5.3.2 documentation.

In 7.1.3 docs, Developing Reporting Applications, it gets a very minor role with &RETCODE on page 6-91! Initially it was DOS STATE, but STATE works now.

It is a v. useful command.

Is STATE an operating system command? I've just run it on a Windows PC and a UNIX server., but I don't think this will work on a MVS system. You may need to use

-? TSO DSNAME 'FOCUS.DB.NAME' and then check &RETCODE.

I think that STATE was VM (am getting old and forgetful) and ported to PC and thence Unix, so would not work on MVS, maybe not on AS400 either.

Thanks. The idea appeal to me.... but the STATE command does not exist :
" (FOC1517) COMMANDE NON RECONNUE STATE UPNBCE1"

They don't install all the functionnality of WF
Version : 526
Gen : 061804

Delphine

Thanks for the command.
"-? TSO DSNAME 'path/dsname' "

My procedure is OK.

Thank you very much

Delphine,

Si STATE n'est pas reconnu et "-TSO DDNAME ..." l'est, cela veut peut-etre dire que le serveur de WebFocus est MVS. Sur ce systeme la commande n'existe pas. Sur les autres (VM, WIN, UNIX, LINUX etc.), oui.
Bon FOCUS!

Daniel,

En effet le serveur de WF est MVS .... Par contre sais-tu comment récupérer le path name afin d'éviter de la mettre en dur pour utiliser "-? TSO DSNAME 'path.nomfic' " ?

J'ai essayé ça sur un fichier existant et le DSNAME est à blanc ....
-? TSO DDNAME 'fic'

'State' tests for the existence of a file or ds. Been using it since back in mainframe focus 3.8 ( sheesh so long ago)...

Francis Mariani

I would guess NOT on MVS Mainframe.

Unfortunately the WHENCE command will not really help Delphine, I think she requires a method to retrieve the DSNAME into a Dialogue Manager variable which is then used in the -? TSO DSNAME command, n'est-ce pas?

Normally,

-? TSO DDNAME [i]ddname[/i]

should work, if, of course, the DDNAME in question is actually allocated to the FOCUS session. If the file exists, &DSNAME is populated with the DSNAME, if it does not exist, &DSNAME is set to blank.

Delphine, is it possible that the file is not allocated to the FOCUS session?

Exactly! And I can check the DSNAME with -? TSO DDNAME .... I try it but i write it wrongly.... (sorry my english is very bad)...

It's OK now... thanks a lot

Francis,

Française....

Si je peux écrire français... chouette...
Au fait .... j'ai un soucis avec -? DSNAME et DDNAME ...!!

La façon dont c'est monté le DSN est créé automatiquement en début d'exécution en batch... à tous les coups il le trouve alors que le master n'est pas créé.... dommage.... ça marchait très bien en intéractif

Have a good day ....

On n'a pas besoin d'un Master pour les commandes -? TSO DSNAME/DDNAME. Pour garder le Master crée par ON TABLE HOLD AS ..., assigner DDNAME HOLDMAST a un PDS existant.

Sorry, my written French is not perfect.

I don't think we need a Master to execute -? TSO DSNAME/DDNAME. To keep a Master created by ON TABLE HOLD AS ..., allocate DDNAME HOLDMAST to an existing PDS.
