Have a look at "paramstr" (
https://www.freepascal.org/docs-html/rtl/system/paramstr.html
).
You could execute a console/command-line with something like:
prog 42 foobar.txt
^0 ^1 ^1
within the program you access the parameters with code like
Code: Pascal
[Select]
[+]
[-]
program_exe
:
=
paramstr
(
0
)
;
some_number
:
=
paramstr
(
1
)
;
some_filename
:
=
paramstr
(
2
)
;
In Windows, you can also create a short-cut, then specify parameters, to run the program in a GUI.
cheers

I am not sure what you mean.
To add parameters to a short-cut:
right-click on the short-cut file (in windows explorer) and select "properties"; you can add the parameters after the EXE name (in Target).
To add parameters inside Lazarus IDE (for testing etc):
select "Run > Run Parameters" then add your parameters into "Command line parameters".
To check what parameters there are, I'd suggest using the FormCreate() procedure. Something like the code below.
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
FormCreate
(
Sender
:
TObject
)
;
var
a
:
byte
;
begin
memo1
.
append
(
'paramcount = '
+
paramcount
.
tostring
)
;
for
a
:
=
0
to
paramcount
do
memo1
.
append
(
'param '
+
a
.
tostring
+
' = '
+
paramstr
(
a
)
)
;
end
;
cheers
