Function

The TERMINATE statement is used to terminate a Natural session. A TERMINATE statement may be placed anywhere within a Natural program. When a TERMINATE statement is executed, no end-of-page or end-loop processing will be performed.

The behaviour of the TERMINATE statement matches that of the STOP statement. Processing of return values is not supported.

For Natural RPC: See Notes on Natural Statements on the Server in the Natural RPC (Remote Procedure Call) documentation.

Note:
The use of the TERMINATE statement is discouraged within dialog-based applications. For more information, see Using the TERMINATE or STOP Statements Within Dialog-based Applications in the Programming Guide.

Syntax Description

Operand Definition Table:

Operand	Possible Structure					Possible Formats												Referencing Permitted	Dynamic Definition
operand1	C	S					N	P	I									yes	no
operand2	C	S	A			A	U											yes	yes

Syntax Element Description:

Syntax Element	Description
operand1	operand1 may be used to pass a return code to the program receiving control when Natural terminates. For example, a return code setting may be passed to the command processor and then checked with the function ERRORLEVEL. See also Natural Startup Errors in the Operations documentation. The value supplied for operand1 must be in the range 0 - 255.
operand2	operand2 may be used to pass additional information to the program which receives control after the termination.

Program Receiving Control after Termination

After the termination of the Natural session, the program whose name is specified with the profile parameter PROGRAM will receive control.

Natural passes operand2 and the value of the profile parameter PRGPAR to that program, if they are specified. The program receives these parameters in the usual way as arguments:

int main(int argc, char *argv[])
{
  /* Number of arguments passed. */
  printf("Number of arguments: %d\n", argc);
  /* Program name. */
  if ( argc > 0 )
    printf("Program: %s\n", argv[0]);
  /* Value of operand2 of the TERMINATE statement. */
  if ( argc > 1 )
    printf("Operand 2: %s\n", argv[1]);
  /* Value of the profile parameter PRGPAR. */
  if ( argc > 2 )
    printf("PRGPAR: %s\n", argv[2]);
  return 0;
}

If the PROGRAM parameter is not set, the command interpreter will receive control after the termination.
