That made it clearer. You can do this clear input date str1 variable1ab str1 variable2cd 1 q w 2 e r end label var variable1ab "A B" label var variable2cd "C D" save aroratest longshape variable*, i(date) j(whatever) . l +-----------------------------------+ | date whatever _whatever y | |-----------------------------------| 1. | 1 A B variable1ab q | 2. | 1 C D variable2cd w | 3. | 2 A B variable1ab e | 4. | 2 C D variable2cd r | +-----------------------------------+ It then sounds like a case for -split- on -whatever-. The key to this solution was posted fairly recently, -longshape- from SSC. -ds- and -findname- find variable names, but string values within the data are not where it looks. I still see no connection with this problem, despite being very familiar with both commands, but if -longshape- helps with a solution, I guess that is immaterial.
