Jian:

The way JCL is written is these files get appended,  you may want to read
them as two separate files into two separate datasets,  do your assignment
statements and then append the SAS datasets.  That's one way to do it.

Like
JCL:
//PER1 DD DSN=CC37. NHIS70.PERSONSX, DISP=SHR, UNIT=TAPE80
//PER2 DD DSN=CC37.NHIS80.PERSONSX, DISP=SHR, UNIT=TAPE80

data persons1;
infile per1;
input year 20 location 21 sex 23;
if year=0 then year=70;
run;

data persons2;
infile per2;
input year 20 location 21 sex 23;
if year=0 then year=80;
RUN;


PROC APPEND BASE=PERSONS1 DATA=PERSONS2;
RUN;

Hi, All SAS users:

I have a question. Following is mainframe JCL and some SAS codes.

JCL:
//PER DD DSN=CC37. NHIS70.PERSONSX, DISP=SHR, UNIT=TAPE80
//    DD DSN=CC37.NHIS80.PERSONSX, DISP=SHR, UNIT=AFF=PERSON
...

data persons;
infile per;
input year 20 location 21 sex 23;
???if year=0 then year=70(if year=0 comes from NHIS70.PERSONSX) or year=80
(if year=0 comes from NHIS70.PERSONSX)
....
....

There is one variable named YEAR which exists in both of the two files.
YEAR=0 in these two files, that is, NHIS70.PERSONSX and NHIS80.PERSONSX.
How can I do the following:
when year=0 comes from NHIS70.PERSONSX, I want to assign year=70, when
year=0 comes from NHIS80.PERSONSX, I want to assign year=80.

Thanks a lot!
