Subject   st: implementing a pattern to match numbers with ranges

Dear all,

I have many numbers with 4 digits, like 0100, 2044,... (this variable is called "SIC"). Now I want to match this number to a two-digit number (this new variable is called "Industry").

The matching should be like this:

0100-0799,2048-2048=03
2000-2046,2050-2063,2070-2079,2090-2095,2098-2099=23
2064-2068,2086-2087,2096-2097=47
2080-2085='08'

One example: variable "SIC" is given with the value 0100. Then Stata should give variable "Industry" the value 03 for this row.

I am looking for a way to implement this pattern. I hope there is someone with an idea...

Thanks a lot,
Silke R.
