Dear members,

I have a dataset  in wide format where the variables are

id     x73_24   x74_24    x75_24    x87_24   x99_24   x00_24
...     ...      ...        ...      ...      ...      ...

where the first two numbers  in, for example, x73_24 indicate the year. It is a variable indicating whether there are less than 24 crimes in 1973 in city id; x00_24 indicates  whether there are less than 24 crimes in 2000 in city id, and so on...

I have specified 
reshape long x@_24, i(id), j(year)
after reshape stata displays
note: j=0 73 74 75 87 99
note: x0_24 not found

if instead I write
reshape long x@_24, i(id), j(year 73-75 87 99 00)

stata does not give that messagge. Is this because stata does read "00" as a "0" and thus does not recognize any x0_24?  
 And would be correct to apply the second specification? Looking at that the data it seems correct to me but I would like to be sure

Thank you for any help
Sara Borelli
