st: scripting question (_n) |

Hi,

I have a variable (var1) like this:

var1

a

a

a

a

a

b

a

a

a

b

a

... (there are several thousand of these)

I want to creat a unique number to identify each set from a-b. e.g.:

var1 var2

a 1

a 1

a 1

a 1

a 1

b 1

a 2

a 2

a 2

b 2

a3

...

I know how to use the _n command, but am unsure of how to employ it in this case (i can do it in the opposite order). any help would be appreciated.

kelly
