I have a VSAM File Say ABC.ABC.ABC.

the Layout of the VSAM File is
Code:

02 Key
     05  a    pic x(30)
     05  b    pic 9(10)
02 Data
     05  c    pic x(30)
     05  d    pic 9(10)
     05  e    pic x(30)
     05  f    pic 9(10)
     05  g    pic x(30)
     05  h    pic 9(10)


Now I need to create a Single Alternate Index file for ABC.ABC.ABC having "e" "a" and "b" as alternate Key..
Please advise whether this can be acheived, if yes, Please provide me an example

looks like You did not pay attention to the manual

for vsam the keys ( primary and alternate ) can consist only of contiguos bytes

if You need a key build from different fields You must restructure Your record layout
