EXIT

Description

The EXIT statement halts the execution of a program and returns a numeric exit code to the parent process.

It takes the general form: 

EXIT(expression)

or

EXIT


where the expression must evaluate to a numeric result, which should be the appropriate error code for the environment in which jBASE is being run. The error code is returned to the parent C function exit(). 

Note: 

  • For compatibility with older versions of the language, the EXIT statement should be used without an expression. In this case, it is synonymous with the BREAK statement.
  • If the expression does not evaluate to a numeric result the program will enter the debugger and display a suitable error message.
  • The expression has been forced to be parenthesized to avoid confusion with the EXIT statement without an expression as much as is possible.

Assuming a file has been opened to FileDesc, an example of use is as follows:

0001     READ Record FROM FileDesc, RecordKey
0002     ELSE CRT "Record ":RecordKey:" is missing"
0003         EXIT(1)
0004     END


See also: BREAK.
