Sort to pull out unpaired fields

Using sort comparing two files and pulling out the unpaired:

//SYSIN DD *
       JOINKEYS FILE=F1,FIELDS=(1,6,A)
       JOINKEYS FILE=F2,FIELDS=(1,6,A)
       JOIN UNPAIRED,F1,ONLY
       SORT FIELDS=COPY
/*

here the F1&F2 represents file one and file two these two files are compared and the un-matching fields are taken out separately.

The fields 1 - represents initial position of the key, 2 - represents length of the key and A- represents the type of character.

Unpaired keys from file one will be taken out and put into separate file.

File - F1
A00001
B00001
C00001
D00001

File - F2
A00001
C00001

Output
B00001
D00001
