According to Orlando Llanes:
@samp{ParamCount} returns the number of command-line argumentsseperated by spaces
^^^^^^^^^^^^^^^^^^^ Misleading. A UNIX shell can even pass parameters *containing* spaces when they are surrounded by quotation marks or such.
present after the program is executed.
Also misleading: This sounds for me as if the parameters aren't present until the program has finished.
@samp{ParamCount} returns 0 <1?>
0.
if the only statement on the command-line is the name of the program.
This implies that you are invoking the program from a command line. It can also be invoked from another program, in particular a GUI.
I suggest the following:
@c ----------------------------------------------------------------------------
@node ParamCount @unnumberedsec ParamCount @cindex ParamCount
@unnumberedsubsec Syntax
@smallexample Function ParamCount: Integer; @end smallexample
@unnumberedsubsec Description
@samp{ParamCount} returns the number of command-line arguments given to the program. @samp{ParamCount} returns 0 if no arguments have been given to the program; the name of the program as an implicit argument is not counted.
@unnumberedsubsec Standards
@samp{ParamCount} is a Borland Pascal extension.
@unnumberedsubsec Example
@example Program Test;
Var i: Integer;
begin writeln ( 'You have invoked this program with ', ParamCount, ' arguments.' ); writeln ( 'These are:' ); for i:= 1 to ParamCount do writeln ( ParamStr ( i ) ); end. @end example
