Does XOJO have a keyword for setting a number base such as 0 to 7 or 0 to 4 etc?

and &b for binary:

and &h for hex:

https://documentation.xojo.com/%26h

TBH I’m not sure what it is you mean ?

Do you literally mean to specify the numeric base a number is expressed in (base 2 for binary, octal for base 8 hex for base 16, and base 10 which is the usual default) ?

Or something else ?

I was looking for a way to incrementing a number like this:

0,1,2,3,4,5,6,7,10,11,12,13,14,15,16,17, 20, 21, 22, etc.

or even better:

1,2,3,4,5,6,7,1,2,3,4,5,6,7,1,2,3,4,5,6,7 etc

Used to increment the day of the week and always wrapping back to 1 after 7

nothing built in that would let you define the range of a given value in a simple way

you’d need to apply modulo arithmetic yourself

or bit masking with &h07 (&b0111) or something similar

Thanks Norman. It was very easy to do with if/then or Select Case statements. I just wanted to know.

Just count with a regular integer and use (MyInteger mod 7)+1 to get a number from 1 to 7.

MyInteger = (myInteger + 1) and &h07

should do it as well

These both look like what I was searching for but what seems to give me the correct answer is:

(myInteger Mod 7) without the 1 added. 8 yields a 1, 15 yields a 1, etc.

But 7 will be 0.

If you need 1 to 7 then you will need to check if you get 0 to convert that to 7.

Your right because 8 yields a 2 if you add the +1. So your now back to adding an if/then statement. Nothing gained yet.

I am looking for 1 to 7

You can use:

https://documentation.xojo.com/api/data_types/datetime.html#datetime-dayOfWeek

What do you want to do?

In this particular case I am asking my program to look up array values of temperatures or on/off times that are associated with days of the week. If it’s day 7 and I wish to look ahead a day I want the array element number 1, not 8 or 0

What Alberto says is (from LR):

https://documentation.xojo.com/api/data_types/datetime.html#datetime-dayOfWeek

Use DateTime.DayOfWeek:

The day of the week as an integer: 1=Sunday, 7=Saturday.
