PL1 – PL I – Programming Language One

Table of Contents

PL 1 or PL I (Programming Language One) is part of the mainframe dependencies engine in AWS Blu Insights. It is handled among all other types of files, including Cobol for example. Below are listed the supported statements for dependencies detection.

 

XINCLUDE / -INC / ++INCLUDE / %INCLUDE

The call on -INC implies dependencies on .CPY, .PLI, .PL1 or .INC files.

  • XINCLUDE / -INC /++INCLUDE ‘FILE’
  • XINCLUDE / -INC /++INCLUDE “FILE”
  • XINCLUDE / -INC /++INCLUDE FILE

 

PROC

We expect to find dependencies of any extension.

  • FILE: PROC

 

CALL

We expect to find dependencies of any extension.

  • CALL FILE

It’s also possible to call a procedure with the same syntax

  • CALL PROC

If the procedure is declared inside the file or inside an included file (via a %INCLUDE for example) it will create no dependency.
Also, if the called procedure is declared as a parameter of type entry (or an alias of entry), no dependency will be created, as the name of the procedure will be given dynamically.

A call to a procedure declared extern or generic will not be considered as a missing dependency.

  • DCL myExtProc Ext Entry(FORMAT);

  • DCL myGenericProc            Generic

Here myExtProc is declared as an external procedure and myGenericProc as a generic procedure, they will not appear in the dependencies.

 

EXEC CICS
DELETE / READ / WRITE / REWRITE FILE

We support several calls on DELETE / READ / WRITE / REWRITE _FILE_, the call itself could be on multiple lines or not. We expect to find dependencies of any extension but .CBL, .COB and .CPY.

  • EXEC CICS DELETE / READ / WRITE / REWRITE FILE(“FILE”) … END-EXEC
  • EXEC CICS DELETE / READ / WRITE / REWRITE FILE(‘FILE’) … END-EXEC
  • EXEC CICS DELETE / READ / WRITE / REWRITE FILE(FILE_VAR) … END-EXEC that implies dependencies on the values of FILE_VAR including its initial value and all the values set with a MOVE ... TO _FILE_VAR_ operation. The variable can be declared in the same file as the call or in one of its imported copybooks.

 

LINK / XCTL PROGRAM

We support several calls on LINK _PROGRAM_, the call itself could be on multiple lines or not. We expect to find dependencies of any extension.

  • EXEC CICS LINK / XCTL PROGRAM(“PROGRAM”) … END-EXEC that implies a dependency on a file named “PROGRAM”
  • EXEC CICS LINK / XCTL PROGRAM(‘PROGRAM’) … END-EXEC that implies a dependency on a file named “PROGRAM”
  • EXEC CICS LINK / XCTL PROGRAM(PROGRAM_VAR) … END-EXEC that implies dependencies on the values of _PROGRAM_VAR_ including its initial value and all the values set with a MOVE ... TO PROGRAM_VAR operation. The variable can be declared in the same file as the call or in one of its imported copybooks.

 

SEND / RECEIVE MAP and SEND / RECEIVE MAPSET

We support several calls on RECEIVE MAP, the call itself could be on multiple lines or not. We expect to find dependencies of any extension but .CBL, .COB and .CPY :

  • EXEC CICS SEND / RECEIVE MAP / MAPSET(“_MAP_”) ... END-EXEC that implies a dependency on a file named “MAP”
  • EXEC CICS SEND /RECEIVE MAP / MAPSET('_MAP_') ... END-EXEC that implies a dependency on a file named “MAP”
  • EXEC CICS SEND /RECEIVE MAP / MAPSET(_MAP_VAR_) ... END-EXEC that implies dependencies on the values of MAP_VAR including its initial value and all the values set with a MOVE ... TO MAP_VAR operation. The variable can be declared in the same file as the call or in one of its imported copybooks.

 

EXEC CICS … TRANSID
  • EXEC CICS exec-cics-verb TRANSID(“transaction-name”) ... END-EXEC implies a dependency on a “TRANSACTION” object named “transaction-name”
  • EXEC CICS exec-cics-verb TRANSID('transaction-name'”) ... END-EXEC implies a dependency on a “TRANSACTION” object named “transaction-name”
  • EXEC CICS exec-cics-verb TRANSID(variable-name) ... END-EXEC implies a dependency on all “TRANSACTION” objects referenced by the variable “variable-name”

“exec-cics-verb” can be one of the following

  • START: start transaction
  • RETURN: return transaction

 

EXEC SQL

We support several calls on EXEC SQL, the call itself could be on multiple lines or not. We expect to find the dependencies of any extension. The dependencies are detected for the following operations in the request :

  • EXEC SQL ... FROM TABLE1, TABLE2 ... END-EXEC where TABLE1 and TABLE2 are files corresponding to SQL tables. TABLE2 is optional and if there are only two tables, commas aren’t needed.
  • EXEC SQL ... INSERT INTO TABLE1 ... END-EXEC where TABLE1 is a file corresponding to a SQL table.
  • EXEC SQL ... JOIN TABLE1 T1 ON ... END-EXEC where TABLE1 is a file corresponding to a SQL table and T1 is an optional alias for TABLE1 used in the rest of the request.
  • EXEC SQL ... UPDATE TABLE1 SET ... END-EXEC where TABLE1 is a file corresponding to a SQL table.

 

EXEC SQL INCLUDE / SOURCE

The call on EXEC SQL INCLUDE implies dependencies on .CPY, .PLI, .PL1 or .INC files.

  • EXEC SQL INCLUDE / SOURCE '_FILE_' ... END-EXEC
  • EXEC SQL INCLUDE/ SOURCE "_FILE_" ... END-EXEC
  • EXEC SQL INCLUDE/ SOURCE _FILE_ ... END-EXEC
