Issue/Introduction

Description:

The DCB for Earl SYSEARL can vary depending on the OPTION PRINTER=nnn. How can I determine the DCB?

Solution:

The DCB for SYSEARL can be a bit tricky.

If no DCB is specified, the LRECL is dependent upon the OPTION PRINTER=nnn size.
The PRINTER=nnn is limited to 216.

If no DBC is specified, the RECFM will default to FA.
When FA, the LRECL is PRINTER nnn+1 to accommodate the carriage control character.
You can allocate SYSEARL with LRECL greater than the PRINTER=nnn size (maximum of 216) but the actual formatted print line will be the size of the PRINTER=nnn value.

The resulting RECFM will be FA or FBA.
While FA is the default, FBA will result when you provide full DCB of RECFM, LRECL, and BLKSIZE. RECFM FB, VB, or VBA will be overridden by Earl.

There is a special APAR LS67896 which will allow you to specify BLKSIZE=0. Since this is a "custom" APAR, it is not sourced into Earl Service or CA Earl products and you would have to SMP/E RESTORE and re-apply LS677896 for each new service pack of Earl Service in CA Common Services or CA Earl.

A series of tests were run to illustrate the results using various DCB.

In the following chart, the Test Name can be interpreted as:

LnnnDEF    test with OPTION PRINTER=nnn and
           allowing SYSEARL DCB to default.
Lnnnxxx    test with OPTION PRINTER=nnn and
           SYSEARL allocated with
           DCB=(RECFM=xxx,LRECL=nnn,BLKSIZE=0)
   
ZnnnDEF    test with APAR LS67896 and
           OPTION PRINTER=nnn and
           allowing SYSEARL DCB to default.
Znnnxxx    same tests as Lnnnxxx with APAR LS67896 applied.
           Note, the only difference was when FBA not specified.
