lineno
: Line numbers are integer values that specify a line number to match. 
Using 0 matches all line numbers.
–x
: Skips the first line of the source code, which may have special instructions that you don’t 
need for the current session.
IronPython doesn’t support all of the CPython command line switches. 
Consequently, you may find that a batch file written to execute a CPython 
application won’t work properly with IronPython. For example, IronPython 
doesn’t appear to support the PYTHONHOME environment variable. All 
IronPython environment variables begin with IRON, so you need to modify 
batch files to include this first word as part of any environmental variable setup.

Working with the –X: Command Line Switches
In addition to the standard command line switches, you also have access to the –X: command line 
switches, which configure the IronPython interpreter. The following list describes each of the con-
figuration options:
–X:AutoIndent
: Enables auto-indenting in the read-evaluation-print loop (REPL).
–X:ColorfulConsole
: Enables ColorfulConsole support.
