Plus and minus for Enumeration

I've been thinking about this for a while:
Code: Select all
Enumeration 5
#brekn
#eicnx
#rerom
#lvowh +1
#wtbcu
#gbsot
#stbci -2
#dtisx
EndEnumeration
Any takers?!

ö.Ö
... in your example #dtisx would be the same as #wtbcu ... ?
in my eyes, Enumeration is made to get a row of values without gaps and without doubles...
but ok, since we can have = in enums, why not + and - ? *shrug*

I don't think it's readable. It took me a few guesses to figure it out and I'm still not sure if I'm right about what you intended to have happen with that sample code.
Based on my guess I would discourage this feature request.
It can already be done this way:
Code: Select all
Enumeration 5
#brekn
#eicnx
#rerom
#lvowh = #PB_Compiler_EnumerationValue + 1
#wtbcu
#gbsot
#stbci = #PB_Compiler_EnumerationValue - 2
#dtisx
EndEnumeration

+1 (lol!)
I think it should be added, the + would be really useful (possibly the - too, but not as much as the +).

I thought the whole point of Enumeration is to give a set of #Constants a value which are unique in the set.
If you start mucking about adding and subtracting, why bother with the Enumeration at all, why not just define them all yourself.
I can't see any point for this addition (pun not intended).

Should the + just work for that single constant in the line with "+" or should it Step above some numbers for every constant?
Code: Select all
Enumeration 5
#Erste ;=5
#Zweite+5 ;=11 or 10?
#Dritte ;=6 or 11 or 12?
IMHO, an exponential Enumeration could be usefull to create Tags for Procedure Parameters.
You know, like #PB_Window_Invisible=2^28
Code: Select all
Enumeration 2 Exponential
#Tag_Do ;=2
#Tag_Save ;=4
#Tag_Debug ;=8
EndEnumeration
This would be nice

why would you want to do anything like that...
to me you may as well simply be setting that value manually if thats the case
to me enumeration is just that like a for x=1 to 10 and setting each variable in that loop to the new value.. staps in enumeration i can inderstand ie: step 5 .. so it goes up in 5's but to me doing any math or subtraction is not what enumeration is for. but then i guess thats just me
