I do not quite get what you want to achieve. You can certainly turn them
into numeric data types, to be processed further:


*******
clear*

input  str30 other_rash

Subject: st: quick question

I have a list of multiple diagnoses (rashes) and the typical one is quite
rare.  I decided to simply count the number of such diagnoses.  The data
look like (in the first 50 observations)

     +--------------------+
     |         other_rash |
     |--------------------|
 10. |               55.1 |
 11. |                  0 |
 12. |               54.3 |
 13. |                  0 |
 14. |                  0 |
     |--------------------|
 15. |               55.2 |
 16. |                  0 |
 17. |                  0 |
 18. |          17.3;49.3 |
 19. |               55.2 |
     |--------------------|
 20. |          11.3;18.3 |
 21. |                  0 |
 22. |                  0 |
 23. |                  0 |
 24. |      9.2;11.3;17.3 |

 25. |                  0 |
 26. |                  0 |
 27. |                2.1 |
 28. |          15.2;23.2 |
 29. |          19.2;55.2 |
     |--------------------|
 30. |                  0 |
 31. |               11.2 |
 32. |                  0 |
 33. |                  0 |
 34. |                  0 |
     |--------------------|
 35. |                  0 |
 36. |                  0 |
 37. |               57.2 |
 38. | 7.1;11.2;29.2;55.3 |
 39. |                  0 |
     |--------------------|
 40. |       2.2;5.3;39.3 |
 41. |               18.2 |
 42. |          11.3;24.3 |
 43. |           5.2;55.2 |
 44. |      9.3; 10; 57.2 |
     |--------------------|
 45. |               46.3 |
 46. | 7.2;46.1;55.1;57.1 |
 47. |                  0 |
 48. |       5.2;9.2;15.2 |
 49. |        3.2;7.2;9.2 |
     |--------------------|
 50. |                  0 |
     +--------------------+

I would like to be able to count the number of other_rashes - I tried to
find a string function that would do this count, I was unsuccessful.  Am I
missing something?  It's not crucial as I've already done this manually, but
I have several other variables to handle.
