STATA cannot read a vlue of dataXY=.z_

hello folks,

STATA cannot read some entries in a numeric variable with the value  
.z_, which are recording errors in Compustat. Trying to convert them  
to 0 was not possible as STATA somehow does not recognize these  
entries. Any idea what that could be ?

Kind regards

Pascal
