Hi.

I want to sort the following selection list:

A1
A10
A5
BA100
BA11
BA5

alphanumerically, so that the list is first ordered by the variable
length alphabetic prefix and then by the variable length numeric
suffix, ie:

A1
A5
A10
BA5
BA11
BA100

Any idea? Note that I cannot change the strings (ie A1 to A0001, etc).

Thanks

You should be able to... If it's important 'BA' an '11' should even be in
a different column.

What will work, but will produce warnings, is REVERSE(), CAST to integer,
yet another REVERSE, get that string length, CAST the result to integer
again, and that's your number, and get the portion of the string minus the
number characters on the right you found out using the weird cast/reverse
scenario, and that's your 'BA' string.
