Betreff: st: how to reconstruct a minimum acceptable income from a set of
binary variables?

Dear all,
I am dealing with a dataset from a private company and so my data often 
comes in rather strange format and I now came against the following problem:
 
I have a set of individuals who answered questions about desired income. 
It looks as follows:

Individ nmb | Min desired income 500 - 999 | 1000 - 1499 |  1500 - 2000 |
101             |                      0                        
|         0          |           1          |
102             |                      0                        
|         1          |           1          |
103             |                      0                        
|         0          |           1          |
104             |                      1                        
|         1          |           1          |
105             |                      0                        
|         1          |           1          |

Is there a way to automatically recode these binary minimum desired  
income variables into a numerical variable which would state the minimum 
acceptable figure for each individual?
That is some routine which would check "Min desired income 500 - 999" 
and if it equals 1 then would input 500 for the individual in question 
into a newly constructed variable "Minimum acceptable income" and move 
on to the next person and if it equals 0 would look at the value of 
"1000 - 1499" variable and if it equals 1 would input 1000 for that 
person and move on to the next person and if it is 0 would look at "1500 
- 2000" variable?
I would be most grateful for any advice,
Sincerely yours,
Ekaterina
