EXIT

The EXIT statement halts the execution of a program and returns a numeric exit code to the parent process. For compatibility with older versions of the language, use the EXIT statement without an expression. In this case, it is synonymous with the BREAK statement.

COMMAND SYNTAX

    EXIT(expression)

    EXIT

SYNTAX ELEMENTS

Any expression provided must be parenthesized and evaluate to a numeric result. The numeric result is used as the UNIX or Windows exit code, which is returned to the parent process by the C function exit(). If the expression does not evaluate to a numeric result the program will enter the debugger and display a suitable error message.

NOTES

The expression has been forced to be parenthesized to avoid confusion with the EXIT statement without an expression as much as is possible. The authors apologize for having to provide two different meanings for the same keyword

       NEXT V.I
       CRT FMT(V.ARRAY, 'MCP') ;* 1^2^3
