For BS2000/OSD, the SMA JCL generation is always executed in Natural batch mode. If the JCL generation is started online (under TIAM or UTM) SMA submits a batch job which performs the generation.

The generated JCL lines will be written to the SMA system file and are additionally stored in the library JOBLIB (see SMA parameter JOBLIB in parameter group BASIC).

The following naming conventions are used:

Name (Type)	Description
E.Tnnn (J)	Job which copies Software AG product files from tape to disk. nnn represents the last three digits of the tape name.
E.Innn (J)	SMA installation jobs where nnn represents the number of the job (see table below). These jobs mainly consist of CALL-PROCEDURE commands which execute the installation steps.
P.function (J)	Procedures which execute the corresponding functions, for example: P.ASSEMBLE P.LINK P.REPORT P.REPSTORE P.ADALOD etc.
#READ-ME (D)	README file of SMA which contains the following information: News for SMA How to work with SMA Product-specific README files
product.function (D)	Instructions/commands for programs or utilities. product represents the 3-byte product code and function the corresponding function. For example, element NAT.INPLMOD contains the instructions for the Natural INPL utility.

Procedures and data which are used for common tasks are controlled by the internal product @SD111 of SMA. All procedures and jobs use the SDF syntax format of BS2000/OSD. There are still some parts where Software AG uses the ISP syntax format but in general Software AG no longer supports the ISP syntax. Therefore, the support of the internal product @IS111 will end together with the support of SMA version 1.3.1.

The following table shows a list of installation jobs which are often used.

Job Name	Description
E.I030	Create database
E.I050	Load database files
E.I055	Assemble Natural (batch)
E.I060	Assemble Natural parameter module and link Natural (batch)
E.I061	Execute Natural INPL and ERRLODUS
E.I065	Link NAF modules
E.I070	Assemble Natural (TIAM and batch)
E.I080	Assemble Natural parameter module and link Natural (TIAM and UTM)
E.I900	Optional job
E.I999	Set environment installed
E.Z010	Apply Zaps
E.Z020	Apply updates (IUPDs)

A Software AG product is installed by executing the generated installation jobs step by step. The jobs can be submitted online within the SMA application or directly using the ENTER-JOB command of BS2000/OSD, for example, /ENTER-JOB *LIB(JOBLIB,E.I050). The SMA installation jobs, with the exception of job E.Z010 (apply Zaps), do not modify any Software AG product files.

If you modify any element in the library JOBLIB, it is possible that the next JCL generation will overwrite your modification.

The version of the elements in the library JOBLIB can be specified with the SMA parameter JCLGEN-COUNTER.
