st: Removing "." (in string format) from a variable

[Michael Stewart <michaelstewartresearch@gmail.com>]

hello ,

i am working with ICD9 codes and i had to convert the icd-9 codes to
string format
Unfortunately , I got some values like following with only dots (as
shown below).
 |--------------|
 |   996.51 |
 |        .     |
 |        .    |
 |        .    |
 |   327.23 |
 |----------   |
 |        .    |
 |        .    |
 |        .    |
 |        .    |
 |        .    |
 |-------------|
 |    555.9 |
 +----------+

As I try to use the icd9 check commnd, I get that the variable has
invalid icd9 values and following output

. |        .   Invalid placement of period |
. |        .   Invalid placement of period |
 |        .   Invalid placement of period |
 |        .   Invalid placement of period |
 |        .   Invalid placement of period |
|----------------------------------------|

Is there any way to just remove   "." (in string format) from the variable.

Mike.
