Is there a way to retrieve the number of parameters using GPC?

Try "ParamCount " ;-)

BTW, you "misused" the "GPC REFERENCE" subject line which was intended to mark sections of the GPC reference manual posted to this list. Now

I don't know what I was thinking, but I didn't intentionally mis-use the GR subject line. But I did want to add a description to the reference regarding ParamCount.

Now for the reason I asked if GPC had anything to count the number of parameters. I assume I didn't misspell ParamCount because nobody has corrected me, and I also assume that capitalization doesn't matter because it's Pascal, so here goes... I got an error from GPC saying that ParamCount is an undeclared identifier. The following is the program I wrote that gave me the error:

PROGRAM Tmp;

BEGIN WriteLn( ParamCount ); END.

According to Orlando Llanes:

@samp{ParamCount} returns the number of command-line arguments

seperated 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

@unnumberedsubsec See also

@ref{ParamStr}.

@c ----------------------------------------------------------------------------
