ParamCount

[Wilfried Mestdagh]

Hello,

If I do following:
for n := 0 to paramcount - 1 do showmessage(paramstr(n));

Then I have NOT the last parameter on command line, if do:
for n := 1 to paramcount do ..

then I have all parameters. I use Delph5 pro. Seems a bug to me ?

The docs are a bit goofy about this.
ParamCount is the number of PARAMETERS e.g. ParamStr(ParamCount) gives the
last parameter. ParamStr(0) gives the command (e.g. c:\mypath\myexe.exe )
therefore
for n := 0 to ParamCount do
showmessage(paramstr(n));
gives a breakdown of the entire commandline

not really a (code) bug, just poorly documented (which IS considered a bug
in some shops ;)

Why do you think so? Help for ParamStr() --

----------------
Index is an expression of type Integer. ParamStr returns the parameter from
the command line that corresponds to Index, or an empty string if Index is
greater than ParamCount. For example, an Index value of 2 returns the second
command-line parameter.

ParamStr(0) returns the path and file name of the executing program (for
example, C:\TEST\MYPROG.EXE).
----------------

You have n params, numbered from 1 to n, and paramStr(0) always returns the
full path to the current exe.

Nope, no bug. It is working exactly as designed and documented. From
the Delphi help --

"ParamStr returns the parameter from the command line that corresponds
to Index, or an empty string if Index is greater than ParamCount. For
example, an Index value of 2 returns the second command-line
parameter.

ParamStr(0) returns the path and file name of the executing program
(for example, C:\TEST\MYPROG.EXE)."

Thanks, its indeed right documented, it was just confusing because of the
example in the help witch states: fro n := 0 to paramcount - 1

thx, Wilfried

You're right. That example should be changed. I hope Janet sees this (I
changed the subject line). If not, she should be told by e-mail.

What's unclear to you about the ParamCount docs? Makes sense to me...

IMHO,
