COuld you do sth like this...

if you have a saved file containing B1, B2....B8 and you open a file containing A1, A2...A19. Note the latter file is your master file. 




       var1    id |
     |------------|
  1. |   A1   101 |
  2. |   A2   102 |
  3. |   A3   103 |
  4. |   A4   104 |
  5. |   A5   105 |
     |------------|
  6. |   A6   106 |
  7. |   A7   107 |
  8. |   A8   108 |
  9. |   A9   109 |
 10. |  A10   110 |
     |------------|
 11. |  A11   111 |
 12. |  A12   112 |
 13. |  A13   113 |
 14. |  A14   114 |
 15. |  A15   115 |
     |------------|
 16. |  A16   116 |
 17. |  A17   117 |
 18. |  A18   118 |
 19. |  A19   119 |

 

 

 

       var1    id |
     |------------|
  1. |   B1   103 |
  2. |   B2   101 |
  3. |   B3   102 |
  4. |   B4   105 |
  5. |   B5   110 |
     |------------|
  6. |   B6   104 |
  7. |   B7   113 |
  8. |   B8   115 |
     +------------+

 

merge 1:1 id using t1.dta, keep(match master)

 gen check1=string(_merge)=="3"   will give you 

 

var1    id            _merge   check1 |
     |---------------------------------------|
  1. |   A1   101       matched (3)        1 |
  2. |   A2   102       matched (3)        1 |
  3. |   A3   103       matched (3)        1 |
  4. |   A4   104       matched (3)        1 |
  5. |   A5   105       matched (3)        1 |
     |---------------------------------------|
  6. |   A6   106   master only (1)        0 |
  7. |   A7   107   master only (1)        0 |
  8. |   A8   108   master only (1)        0 |
  9. |   A9   109   master only (1)        0 |
 10. |  A10   110       matched (3)        1 |
     |---------------------------------------|
 11. |  A11   111   master only (1)        0 |
 12. |  A12   112   master only (1)        0 |
 13. |  A13   113       matched (3)        1 |
 14. |  A14   114   master only (1)        0 |
 15. |  A15   115       matched (3)        1 |
     |---------------------------------------|
 16. |  A16   116   master only (1)        0 |
 17. |  A17   117   master only (1)        0 |
 18. |  A18   118   master only (1)        0 |
