Take Name from 1st record in File1 (POS 12 lenght 30) and find a match on the Name in File2 (POS 1 Lenght 30),
If matched, then copy the data from of File2 (pos 31 lenght 9) bytes and append them to the full record from File1 to create output File 3

Now take Name from 2nd recond in File1 and start at beginning of File2 and look for match...then create File3 the same way as before

Now take Name from 3rd recond in File1 and start at beginning of File2 and look for match...If cannot find a match then just take full file2 and write out with 'NO MATCH' appended.

File 1
Code:
54868452200ABACAVIR SULFATE           
00173066400ABACAVIR SULFATE           
54569559400ABACAVIR SULFATE/LAMIVUDINE
68158014951ABARELIX


File2
Code:
ABACAVIR SULFATE              001730661
ABARELIX                      575160149
ABCIXIMAB                     000027140
ABROTANUM TINCTURE            153610101
ACACIA                        369870026


File3
Code:
54868452200ABACAVIR SULFATE               001730661
00173066400ABACAVIR SULFATE               001730661
54569559400ABACAVIR SULFATE/LAMIVUDINE    NO MATCH

Here's a DFSORT/ICETOOL job that will do what you asked for. I assumed your input file has RECFM=FB and LRECL=80, but the job can be changed appropriately for other attributes.

Code:

//S1 EXEC PGM=ICETOOL
//TOOLMSG DD SYSOUT=*
//DFSMSG DD SYSOUT=*
//IN1 DD DSN=...  input file1 (FB/80)
//IN2 DD DSN=...  input file2 (FB/80)
//T1 DD DSN=&&T1,UNIT=SYSDA,SPACE=(CYL,(5,5)),DISP=(MOD,PASS)
//OUT DD DSN=...  output file (FB/80)
//TOOLIN DD *
COPY FROM(IN2) TO(T1) USING(CTL1)
COPY FROM(IN1) TO(T1) USING(CTL2)
SPLICE FROM(T1) TO(OUT) ON(12,30,CH) KEEPNODUPS -
  WITHALL WITH(1,11) WITH(81,1) USING(CTL3)
/*
//CTL1CNTL DD *
  INREC BUILD=(12:1,30,43:31,9,81:C'BB')
/*
//CTL2CNTL DD *
  INREC OVERLAY=(43:C'NO MATCH',81:C'VV')
/*
//CTL3CNTL DD *
  OUTFIL FNAMES=OUT,OMIT=(81,2,CH,EQ,C'BB'),
    BUILD=(1,80)
/*
