Hi ,

I'm trying to Dynamicaly Allocate File via OPEN FILE (OUT) TITLE('DSN(XXXXX.XXXXX.MILTEST),LRECL(80)'); 

File is created but the record size is default value; I tried env variable and alternate name with DD_DDNAME but keep getting

UNDEFINEDFILE condition was raised ABENDU4038

thanks

That looks like z/OS.

You'll need to look in the Programming Guide.

Hi Milan,

I'd use BPXWDYN to do the allocate. Then open the allocated file. Separating allocate from open make diagnosis a bit simpler.

Here are some links to documentation for BPXWDYN :

• ftp://ftp.software.ibm.com/s390/zos/tools/bpxwdyn/bpxwdyn.html
• https://www-01.ibm.com/support/knowledgecenter/SSLTBW_2.1.0/com.ibm.zos.v2r1.bpxb600/wdyn.htm

The doc contains examples of how to fetch and call it from PL/I.

Good luck.

Hi,

I use code like this:

DCL OUT FILE RECORD OUTPUT  ENV ( VB RECSIZE (120)      );

 OPEN FILE (OUT)  TITLE                                             
    ('DSN('!!CURRENT_DSN!!')'                         
     !!',NEW,CATALOG'                                 
     !!',TRACKS'                                      
     !!',SPACE(50,1)'                                 
     !!',DATACLAS(RETP0007)'                          
     );                       

You can use a lot more DSN-Options (STORCLAS(whatever), MGMTCLAS(whatever), ..). Have a look in PL/1 Programming Guide.

Hello Milan,

that's not a correct PL/1 Syntax, you produced. The apostrophe in front of "TSMOS.COMPILER..." terminates the string. So the compiler uses TSMOS.COMPILER.MILTEST as a reference to a variable.
Use TITLE (' << string with all the options - one of them is DSN(dsname) - others are NEW, CATALOG, and so on --->')

OPEN FILE (OUT) TITLE
(    'DSN(TSMOS.CIMPILER.MILTEST),NEW,CATALOG,TRACKS,SPACE(50,1)'  );

should work.

In my example CURRENT_DSN is a variable (CHAR (48) VAR) variable which is filled before the OPEN.

I attached a stripped version of  my log-writer to illustrate how we use it (DSN is bulit with a fix suffix and some timestamp-related parts).

Note: in the installation where I'm currently working "!!" (two exclamation marks) are used for concatenation (not the common "||"s). Probably you've to change my sample-code on your system. 

Regards,

Tom

thanks a lot Tom, it worked, much appreciated
