HI,

We have a code as below...

Code:

JOINKEYS F1=IN1,FIELDS=(1,18,A) 
JOINKEYS F2=IN2,FIELDS=(4,18,A) 
JOIN UNPAIRED,F2                 
REFORMAT FIELDS=(F2:1,457,?)     
OPTION COPY                     


I know the meaning of all other but can I know what the below question Mark (?) denotes here?

Code:

REFORMAT FIELDS=(F2:1,457,?)


Thanks
KSK

Code:
//STEP0100 EXEC PGM=SORT
//SYSOUT   DD SYSOUT=*
//INA      DD *
AAA
ACC
BBB
CBB
DBB
EBB
FBB
//INB      DD *
AAA
BCC
BBB
CBB
DBB
EBB
FBB
//SORTOUT  DD SYSOUT=*
//SYSIN    DD *
  OPTION COPY
  JOINKEYS F1=INA,FIELDS=(1,5,A)
  JOINKEYS F2=INB,FIELDS=(1,5,A)
  JOIN UNPAIRED F1,F2
  REFORMAT FIELDS=(F1:1,5,F2:1,5,?)
//*


Gives an output

Code:
AAA  AAA  B
ACC       1
BBB  BBB  B
     BCC  2
CBB  CBB  B
DBB  DBB  B
EBB  EBB  B
FBB  FBB  B


So using ? in reformat could get you three possible values B,1,2

B - When key is found in both files
1 - When key found in first file only
2 - When key found in second file only

Read upon the 4.5 REFORMAT Statement in the following link which explains in detail about the Joinkeys parameters.
