Details

This function recognizes the &b (binary) and &h (hexadecimal) prefixes. It can be invoked implicitly through the word_var = string_var expression (see example below). The compiler is smart enough to pre-calculate constant-only expressions involving implicit use of the val function.

Beginning with the release of TiOS 2.0, this function also plays the role of the vali function, which has been removed.

Examples

Tibbo BASIC

							dim w as word
							dim sh as short
							dim s as string
							 
							s="&hF222"
							w = val(s) 'explicit invocation, result will be 61986
							sh= val(s) 'explicit invocation, result will be -3550 (sh is a 16-bit signed variable)
							w = s 'implicit invocation
							w = "2402" 'be calculated at compilation -- no actual val function invokation will be here
