Issue/Introduction

How to make Easytrieve macros and program source managed by Librarian available to Easytrieve compile.

 

Resolution

Solution:

For possible approaches to achieve this, see the steps below:

1. Using FAIR (EZT 6.4) for macros and the subsystem for SYSIN EZTPOPT could be generated with:

   MAC#LIB=2, C
   MACDDN=MASTER, C
   MACRO=LIBR, C

   Then the following assignments in JCL is to be used:

   ...
   //MASTER1 DD DISP=SHR,DSN=<eztplus.macros.master>
   //MASTER2 DD DISP=SHR,DSN=<eztplus.source.master>
   ...
   //SYSIN DD DISP=SHR,DSN=<eztplus.source.master>(<member<),
   // SUBSYS=<lam>
   ...

   The preceding coding requires that Librarian FAIRxxxx modules are available from STEPLIB concatenation or linklist.
   
   
2. Using the subsystem for macros and SYSIN
   
   
   1. For EZT 11.x the following ( default ) setting can be used in EZOPTBL:

      MAC#LIB 1
      MACDDN PANDD
      MACTYPE D

      The JCL assignments then look like:

      ...
      //PANDD DD DISP=SHR,DSN=<eztplus.macros.master>,
      // SUBSYS=<lam>
      // DD DISP=SHR,DSN=<eztplus.source.master>,
      // SUBSYS=<lam>
      ...
      //SYSIN DD DISP=SHR,DSN=<eztplus.source.master>(<member<),
      // SUBSYS=<lam>
      ...

   2. The above JCL ( from EZT r11.x ) works for EZT 6.4 as well, if EZTPOPT is generated with:

      MAC#LIB=1, C
      MACDDN=PANDD, C
      MACRO=PDS, C
      ...

Agenda:

<eztplus.macros.master> identifies the Librarian master file containing macros
<eztplus.source.master> identifies the Librarian master file containing program sources
<member> identifies the program (member) name <lam> identifies the name of the Librarian/AM subsystem

Remarks:

The Librarian subsystem must be active, either initialized during CAS9 processing or by executing LJxxINIT, where xx is the release of Librarian (42 for LIBR 4.2; 43 for LIBR 4.3)

It is recommended to create a language type for Easytrieve sources, using the LUELIGEN JCL to assemble and link ELIPSGEN with following being specified as a sample:

...
ATYPnn=(EZTRIEV,EZT,81,6), X
...

where nn is the first unused suffix of the ATYPExx options in the ELIPSGEN macro.
