Observation 1

EnumerationBinary 0
  #a
  #b
  #c
EndEnumeration  

Debug #a
Debug #b
Debug #c

Output is

0
0
0

but I would expect as output

0
1
2

Observation 2

Code: Select all

EnumerationBinary 5
  #a
  #b
  #c
EndEnumeration  

Debug #a
Debug #b
Debug #c

Output is

5
10
20

Is this actually intended? Does it make sense?
Or should the compiler generate an error message such as "The start constant of EnumerationBinary must be a multiple of 2."?

Yes, it should be a multiple of 2 as it's meant to create 'flag' like enumeration easily. Also, setting 0 as start values makes no sens as 0 will be always wrong when testing with the '&' operation. I will add a compiler check to catch those, thank you.

Yes, I see now. Thanks for the explanation.
