what is the best way to translate "&=~" in pb?

[Thomas Tierney]

Hey,

what is the best way to translate this into PB code

for instance
const bar = 12;

int foo;

foo &=~ bar;

as I read it, it is "anding" the ones compliment of bar?

thanks for any help!!

You'd use "And Not". For example, in C/C++:

DWORD dwFooBar = 0x10030;

dwFooBar &= ~0x20; // dwFooBar is now 0x10010

The equivalent in PowerBasic would be:

Dim dwFooBar As DWORD

dwFooBar = &H10030
dwFooBar = dwFooBar And (Not &H20)

PB also "let"'s you use:

dwFooBar AND= Not &H20

See Let statement in the docs.
