How do you create an error trap.
Can someone please give me a simple example.
This is what i have so far strintok and strint but i need one for real numbers and integers

[TheGuardian001]

All valid integers can be stored as real numbers with intreal (no error check needed).

Real numbers can be safely converted to an int by rounding (no error check needed).

So to sum it up:

String -> Int check: strintok
String -> Int: strint
String -> real check: strrealok
String -> real: strreal
real -> String: realstr
Int -> String: intstr
Int -> Real: intreal
Real -> Int: round
