Assignment of values to constants

[Matthew Berg]

Is the compiler supposed to allow the use of logical operators when assigning values to integer constants? For example, the following code will refuse to compile in PB/DOS v3.5:

%CONST1  = 1
%CONST2  = 2
%CONST3  = %CONST1 OR %CONST2

My PB/DOS manual clearly says that "You can use an expression as long as all parts of the expression are constant." This would work in PB/CC or PB/DLL, so is there some reason why it can't/won't work in PB/DOS?

Equate assignments can include numeric expressions, and the NOT operator only... other bitwise operators are not supported at this time (such as OR, AND, XOR, etc).

The following are valid:
%a = 1
%b = %a + 1
%c = %a * %b
%d = %a \ b%
%e = %a / %b
%f = NOT e%

In that case, I can only hope this issue is on the To Be Fixed list for PB/DOS v4, along with the addition of string constants.

I'll pass your request on to be added to the "wish list" for new features, although I'm fairly sure string equates is already on the list.

Please note that PB/DOS has never supported bitwise operators in equate assignment expressions, so therefore this is NOT actually an "issue" or bug with the compiler!

I surmised it probably wasn't a bug when I tested the same code in PB/DOS v3.2 and got the same result. I guess then it depends on your definition of "issue" - but put it on the New Features list instead if that makes you happier!
