Minor issue with subst

One of our customer files has a field for customer flags that has a length
of 64.  Each position can be turned on with an X in that position.

 

I am having to modify an old RPG III program that checks this flag position
and I must doing something wrong because I am getting far more records than
I should be.

 

Here is the relevant code and my explanation of what I am doing:

 

C                     MOVE *BLANKS   FLGFLD  1    

C           GCUSNR    CHAINCORCSTEX             37

C           *IN37     IFEQ *OFF                   

C           1         SUBSTCXFLGS:28 FLGFLD       

C           FLGFLD    IFEQ 'X'                    

C                     MOVE 'X'       GPRTSM       

C                     ENDIF                       

C                     ENDIF                       

 

I need to make sure that for each pass through the primary file I am working
with a blank FLGLD (which is just my own internal variable) and only if
CXFLGS position 28 has an 'X' in it do I want to update my work file,
although I do not have a line that moves *blanks to it if not equal I did
not think that would have been necessary.

 

Does anyone see any issue with the code as it is written?
