How to decode a long string into individual digits and then sort into boolean

[gch8244]

Basically my job is to take a long string that is just a big list of digits with no commas or spaces in between values into an array of Booleans using the fact that an even number represents a Boolean 'True' and an odd represents a 'False'. I know that to start I must have a format string for a scan from string that gives me each individual number from the length of 65,000 so that I can then put it through a case statement that compares it to odd or even and then put that in a Boolean array. The problem is I don't know what format string I should use to get each individual digit. I've attached the string that I want to convert into Boolean below.

You have asked the question wrong...

Have you thought about using String Subset?

How about a little out-of-the-box thinking here.  You could just use the bytes directly.  Use String To Byte Array.  The values will show up between 0x30 (48) and 0x39 (57).  Notice that the even numbers will still have even values.  So you can just AND with 1 and a simple comparison and you now have an array of Booleans.

How would I then convert that array into an array of 8-bit numbers by using 8 boolean
bits at a time, i.e., the first 8 booleans give a single unsigned 8-bit integer, the next 8 booleans gives the second unsigned 8-bit integer, and so on. The array will thus be reduced in size by a factor of 8.

You need to use the ReshapeArray function, followed by an autoindexing FOR loop with a BooleanArrayToNumber function inside…

It's really esay!
