lval Function

Function:	Converts string representation of a value into 32-bit value (dword or long).
Syntax:	lval(byref sourcestr as string) as dword
See Also:	str, lstr, stri, lstri, bin, lbin, hex, lhex, val

Part	Description
sourcestr	String to convert.

Details

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

Examples

Tibbo BASIC

							dim d as word
							dim l as long
							dim s as string
							 
							s = "4294967295"
							d = lval(s) 'explicit invocation, result will be 4294967295
							l = lval(s) '
							d = s 'implicit invocation, result will be -1 (4294967295 -> &hFFFFFFFF -> -1 for signed variable)
							d = "2402" 'be calculated at compilation -- no actual lval function invokation will be here
