- And how, pray tell did you accomplish that? If you don't specify the /PAD
- option, CONVERT complains of invalid record lengths and doesn't write anything
- to the output file. If you DO specify /PAD, your file is corrupted. Either
- way, CONVERT/FDL does NOT do anything close to what you want. You CAN,
- however, use CREATE/FDL and COPY/OVERLAY to achieve the desired result:
- $ CREATE/FDL=SYS$INPUT: new_file
- RECORD
- FORM FIXED
- SIZE 2048
- CARR NONE
- $ COPY/OVERLAY old_file new_file
