I would like to know this. I want to eliminate only emptype " P and T " records from writing if they have same emp dep value.
Code:
Note : In this example, The Emptype for first two records is " P and T ".
And they have the same empdep value.
Here the EMPTYPE " S" also has the same empdep value.
But it should be written into the output file.
So I would like to avoid only this pair of record from writing into
the output file.
Here's he logic on what I have been working on.
Code:
IF K = SUBSTR(INREC.EMPNO,1,6) THEN DO;
IF P ¬= SUBSTR(INREC.TYPE1,1,4) THEN DO;
WRITE FILE(OUTFILE) FROM (INREC);
END;
ELSE DO;
WRITE FILE(OUTFILE) FROM (HEADER);
WRITE FILE(OUTFILE) FROM (INREC);
END;
END;
END;
K = SUBSTR(INREC.EMPNO,1,6);
P = SUBSTR(INREC.TYPE1,1,4);
READ FILE(INFILE) INTO (INREC);

Your post has been Code'd to preserve formatting. Please do this yourself in future.
You will need to store the P/T records as you only know by the receipt of a T after the P (or P after the T) that the P (or T) is not needed for that key.

The data the TS shows suggests that the records are not necessarily of a fixed format (although heesh might have munged the example by putting explanatory column headers in the Code tags).
Tammi-kun, are more employee types possible than "P", "S", and "T"? May the data be assumed to be sorted by department?
do while (¬eof_tulin);
if (verify(substr(recin,1,1),digits)¬=0) then
do;
recout = recin;
write file (tulout) from (recout);
end;
else do;
p = index(recin,space);
q = verify(recin,space,p);
empdep = substr(recin,1,p-1);
emptyp = substr(recin,q,1);
if (empdep¬=lastdep) then
do;
if (set_aside) then
do;
recout = recaside;
write file (tulout) from (recout);
end;
if (set_aside) then
do;
recout = recaside;
write file (tulout) from (recout);
end;
end foo36;
I have assumed that the first character of EMPDEP is always a decimal digit; that criterion may be used to eliminate header records from consideration. I further assume that, although EMPDEP is always separated from EMPTYP by at least one space (and that it contains no embedded spaces), the record is not of fixed format; thus the use of the INDEX and VERIFY functions to find EMPTYP (if the record is of fixed format, you are better off declaring a structure as suggested by Dr. Sorichetti). An EMPTYP of "P" or "T" causes the record to be set aside and the switch SET_ASIDE to be toggled; when EMPDEP changes, the set-aside record is written if SET_ASIDE is true, which it will not be if a pair of records is encountered. Note that signficantly different data may require changes.
