Summary |
Numeric
The numeric value of the command from the system. |
system-call string-expression
Allows an operating-system-specific command to be executed in an OmniMark program.This operator must be followed by a string expression that contains a system-specific command. system-call
invokes that command and returns the numeric result code returned by that command when it completes its task.
Because the system-call
operator returns a numeric value, it must be used in a context where a numeric expression is required. The string expression contains the name of the program to run, as well as any command-line arguments that are being passed to it.
The function being provided by system-call
and the value it returns depends on the system on which OmniMark is running. The built-in stream #platform-info
can supply some of this information.
