Boolean type (as a bit)

[Kalain]

Hi,

mB 5.0.0.2.
Boolean type is already implemented in mb 5.0.0.2 but there is nothing much about this type in help file. ("Simple type" help file page should be more detailed about this.)
Well, by now any variable declared as boolean type, needs 8 bits.

It would be nice when a variable is declared as boolean to use only one bit and behaves like this :

Code: Select all

dim i, j as boolean
i = 0  ' or i = false
j = not(i)   'j is set to 1 or j is set to true

code as below

Code: Select all

dim i as boolean

i = 25

should return error : out of range.

We are preparing full boolean type for future releases.
Thanks for the tip.

If you're looking into how logic is implemented then it might be a good idea to look into the return values from bit tests, which appear to return 0 for clear and 1 for set which is not the same as "true". I'm NOT saying they need to change it but its a big gotcha as the condition
if not port.bit
always executes.

While on the bool, can we also have array of boolean?
