IDL> w=window()
IDL> p=text(0.3, 0.5,'$\bot$',font_size=20)
IDL> p=text(0.7, 0.5,'$\parallel$',font_size=20)

Subscripts follows the same latex format:

IDL> p=text(0.3, 0.2,'Hello$_\bot$',font_size=20)
IDL> p=text(0.7, 0.2,'there$_\parallel$',font_size=20)

For some reason IDL uses "\bot" rather than "\perp" for the
perpendicular symbol. Huh.

cheers,
