Question

convert alphanumeric to binary

RPGLE, RPG

hi, my program is receivng an "alphanumeric char 10 length " and im using it to chain a PF, but the field from the physical file is binary 9,0, how will i able to convert an alpha10 to binary 9,0 in RPGLE?

Hi,

You should be able to MOVE your character field to your binary field. You'll need to check that you don't have any invalid data before you do the move.

Just to expand on Martin's idea a little bit. The following (as is pointed out in his answer) will work:

 fBinKeyFileif   e           k disk                                  
                                                                     
 dAlphaKey         s             10    inz('0000000002')             
                                                                     
 c                   move      AlphaKey      Key                     
 c     Key           chain     BinKeyFile                         01 
 c     *in01         ifeq      *off                                  
 c     Data          dsply                                           
 c                   else                                            
 c     'Not Found'   dsply                                           
 c                   endif                                           
 c                   move      '1'           *inlr                   
 c                   return                                          
 

where BinKeyFile is defined as:

 R RECORD                
   KEY            9B 0   
   DATA          50      
 K KEY                   
 

BUT there is an assumption being made here, namely that your alphanumeric 10 byte field is using leading zeroes as in the sample program. If, on the other hand, the key value comes into your program as '2 ' then MOVE will toss the '2' due to how 9B 0 fields are implemented. There are ways around this but I won't go into them on the assumption that your field is formatted as above.

To test add a record to BinKeyFile with a key of 2. Using inz('0000000002') as above the record is found on the chain operation. Using inz('2') the record is not found on the chain operation.
