Can you have code run in a terminal and applet?
For example in my program in Main we enter the data for menu and amount of the exchange but the result is displayed in an applet.
works great in the terminal window.
but when using an applet it will not work.

The code I want to use with the applet is [code]import java.awt.*;

if (argNumUnits > 1)
{msgOut ="Metric Conversion Chart" + CRLF + CRLF;
msgOut +="US Standard to Metric" + CRLF ;
msgOut +="-" +" " + CRLF ;
msgOut = argNumUnits +" inches = " + convertedUnits +" centimeters" ;
}
else
{msgOut ="Metric Conversion Chart" + CRLF + CRLF;
msgOut +="US Standard to Metric" + CRLF ;
