create a new data set by 'SET and 'IF'

[Alexxxxxxx]

Dear all

I am using the following codes to create a new sample

data Patstat_gb_hrm_set;
set Dataset.Patstat_hrm_gb_ori;
if SECTOR eq "COMPANY" or "COMPANY GOV NON-PROFIT" or "COMPANY GOV NON-PROFIT UNIVERSITY" or "COMPANY HOSPITAL" or "COMPANY UNIVERSITY";
run;

however, the result is 

60   data Step1.Patstat_gb_hrm_set;
61   set Step1.Patstat_gb_hrm_set;
62   if SECTOR = 'COMPANY' or 'COMPANY GOV NON-PROFIT' or 'COMPANY GOV NON-PROFIT UNIVERSITY' or
62 ! 'COMPANY HOSPITAL' or 'COMPANY UNIVERSITY';
63   run;

Could you please give me some suggestion about this ? especially why Character values been converted to numeric values'?
thanks for your attention to this matter

Try this

data Patstat_gb_hrm_set;
set Dataset.Patstat_hrm_gb_ori;
/*if SECTOR eq "COMPANY" or "COMPANY GOV NON-PROFIT" or "COMPANY GOV NON-PROFIT UNIVERSITY" or "COMPANY HOSPITAL" or "COMPANY UNIVERSITY";*/
if SECTOR in ("COMPANY" "COMPANY GOV NON-PROFIT"  "COMPANY GOV NON-PROFIT UNIVERSITY"  "COMPANY HOSPITAL"  "COMPANY UNIVERSITY");
run;

The if statement requires:

if <condition> then ...

So logically you are saying:

if variable sector equals the string "COMPANY" is true

or the string "COMPANY GOV NON-PROFIT" is true (which is it because its not 0)

etc.

To use if like that you need to put variable and comparitor each time:

if sector="COMPANY" or sector="COMPANY GOV NON-PROFIT" or...
