NimbostratusBinary to decimal
I'm unfortunately stuck and need some help.
I have a variable with a binary value in it. I need to split the value in two; the first 64 bits and the remainder and store these in two new variables. I also need to convert the 64 bits into an 8 digit decimal value.
Any assistance greatly appreciated.

Can you base64-encode an example and post it here? - Magnum_IPKevin - here you go... nVkVI5xxeXvvzbGfFmarAfaDMTRTPnRlKVedR5oqcRGNaZFV8X3HfJ8RCLhIzdM5 My initial requirement is to decode this and store the first 64 bits in one variable and the remainder in another.

I'm not sure what you're expecting the decimal value to be, but here is perhaps one way to do this:
set data "nVkVI5xxeXvvzbGfFmarAfaDMTRTPnRlKVedR5oqcRGNaZFV8X3HfJ8RCLhIzdM5" binary scan [b64decode $data] H* hdata log local0. $hdata set first [string range $hdata 0 15] set last [string range $hdata 16 end] log local0. $first set dec [expr 0x$first] log local0. $dec
