a runtime error that occurs when an arcsine is taken for a user-entered
value—passed in a variable—that is outside of
the permitted range:

Double ld_num

1	Double ld_num

ld_num = Double (sle_1.text)

1	ld_num = Double (sle_1.text)

TRY

TRY

sle_2.text = string (asin (ld_num))

1	sle_2.text = string (asin (ld_num))

CATCH (runtimeerror er)
