how to look at binary variables

[Mark Smith]

The simplest way is:

put numToChar(1) into tByte

this way, tByte is a single byte with the value 0x00000001

For reading the individual bits of returned values, you can use the  
'b' or 'B' format of the binaryDecode function, which will give you  
strings of 1's and 0's.

Best,

Mark
