TERMINATE [operand1 [operand2]]  

This document covers the following topics:

For an explanation of the symbols used in the syntax diagram, see Syntax Symbols.

TERMINATE Usage

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.

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

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 as exit code to the shell.

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 Linux command shell will receive control after the termination.
