CByte Parameter Type error

Don_Kirby · Post by **Don_Kirby** » 22 June 2008, 3:29 AM

Most likely related to the most recent compiler release (V2.5):

Passing a boolean value to CByte returns a compiler error.

Compiler wrote:Error: function "CByte", type conflict parameter 1, formal:Any Numeric, actual:Boolean

Code: Select all

Sub Main&#40;&#41;
Dim X as Byte
X = CByte&#40;True&#41;
End Sub

The value of the boolean does not affect the outcome.

According to the System Library reference CByte does not accept a boolean value. Did this used to work or are you writing new code?

According to the system library reference V2.2.2, Cbyte should accept a Boolean. It's the first type listed in the table of accepted types.

This is from old code. Only the error is new.

You've discovered a hole in the test suite. It should have contained a test for that case (and for CBit and CNibble) which would have revealed the regression.

We've corrected the problem. The change is very localized, coming into play only for those three functions, so I'm making it available immediately for those who need it (ZBasic v2.5.1). After the new version has been fully tested, it will be integrated into the installer.

Thanks for such a quick solution Don.

Sorry I was obviously half asleep this morning. My older hardcopy reference doesn't have it but the 2.2.2 manual does and so does the link I was pointing to
