 This example shows how to pass variables to ReportSmith
}

procedure TfrmRptSmithTst.FormClick(Sender: TObject);
var f : textfile;

begin
{This example assumes you have declared the variable RptVar as a report
variable in ReportSmith}

{Use the initial values property of the Report componant to pass a report variable}
{The syntax is as follows:}

Report1.InitialValues.Add('RptVar=');
{You will have problems passing the '<>' character as the '>' character
gets ReportSmith confused. Instead use something like '~=' and convert
using a ReportSmith macro}

{Also, there is a limit to the total size of parameters. If you need to pass
anything larger than about 256, you must use a temporary file and pass the
file name to ReportSmith. Then write a macro to read the information from the
file:}

AssignFile(f, 'ParmFile.txt');
rewrite(f);
write(f, 'Write the info to a file');
closefile(f);
Report1.InitialValues.Add('FileName=');

{The Run method runs the report}
Report1.Run;

end;

end.
