Having an App fixed in landscape?

[4wheelfurry]

I am running gCalc and would like it to automatically come up in landscape mode WITHOUT turning my phone on landscape first... Is there a way to fix an app to default to landscape when you bring it up??
I have this program mapped to my left softkey and I want to only press one button and it come up in landscape instead of upright...

Take a look at MortScript. Once installed you can write scripts, (easy to do) and map them to keys. Your one key press mapped to a MortScript can
RotateScreen(LandScape), run gCalc, wait, RotateScreen(Portrait)

syntaxt not correct, but you get the idea
