Kill the blank in -missing ()-. Has to be -missing()-. Stata does not always mind blanks, as recently discussed on this list, but here it does. Also, the code around the -replace- line is only for illustration purposes, you do not need it for your particular case...

Dear Martin,
i typed -set obs 1-, 
it came out -obs must be between 28032 and 231975 
             r(198);- in red,

typed -gen  public_medical_insurance_no=""-, 
it came out -public_medical_insurance_no already defined
             r(110);-


typed -replace  public_medical_insurance_no="null" if missing ( public_medical_insurance_no)- 
it came out -missing not found
             r(111);-
Best wishes
Lydia
