Call external program
CALL – Call external program with standard parameters
AS/400 IBMi platform
Call Program This parameter is used to call an AS/400 IBMi program (*PGM) regardless of whether its type is EPM or ILE. This program can be CLP, RPG, COBOL, C, PASCAL, or others.
The name of the library in which the program is located cannot be specified. It must therefore be located in one of the libraries included in the list of libraries. The DD_USRDATA library is always present in the list of libraries.
The program will receive four required parameters which are as follows:
| Parameters | Description |
|---|---|
| 1 | Buffer I |
| 2 | Buffer B |
| 3 | Buffer O |
| 4 | Buffer W |
You can modify the contents of these parameters.
You can enrich the content of O with external data.
Example of a CLP program call:
CALL MYPGM
TRACE W.Field_1 Trace ‘1’
Source CLP
PGM PARM(&I &B &O &W)
DCL VAR(&I) TYPE(*CHAR) LEN(100)
DCL VAR(&B) TYPE(*CHAR) LEN(100)
DCL VAR(&O) TYPE(*CHAR) LEN(100)
DCL VAR(&W) TYPE(*CHAR) LEN(1)
CHGVAR VAR(&W) VALUE('1')
RETURN
Windows platform
CALL ActiveX.class This parameter is used to call an ActiveX dll class.
The class receives five required parameters that are as follows:
| Parameters | Description |
|---|---|
| 1 | Buffer I |
| 2 | Buffer B |
| 3 | Buffer O |
| 4 | Buffer W |
| 5 | Error Message |
You can modify the contents of these parameters.
You can enrich the content of O with external data.

CALLX – Program call with custom parameters
AS/400 IBMi platform
CallX Program [b.Field1/Constant] [b.Field2/Constant] [b.zone3/Constant]
This parameter is used to call an AS/400 IBMi program (*PGM) regardless of whether its type is EPM or ILE.
This program may be CLP, RPG, COBOL, C, PASCAL, and so forth, for which you can specify one to three parameters of your choice.
These parameters can be constants, BASED fields or fields that are not BASED.
Windows platform
CallX DllName.Function [b.Field1/Constant] [I.Field2/Constant] [b.Field3/Constant]This parameter calls a function from a DLL
You will find samples on directory "NT Samples\Transformation\CallX – C"
CallDotNetX – Call DotNet Class from Method call (only windows platform)
CallDotNetX MyDll.MyNameSpace.MyClass.MyFunction [b.Field1/Constant]
[b.Field2/Constant] [b.Field3/Constant]This parameter calls a DotNet Function.
You will find samples on directory "NT Samples\Transformation\CallDotNetX – Csharp".
You will find a sample of WebService call.
