True for '85; not true for '02.
See "SOURCE IS" syntax, starting on page 210 and more detail on 217.
Indeed, I missed that. Raises an interesting question -
"record-key-name-1" is a conceptual item which is the
concatenation of the specified data items.
Can "record-key-name-1" be used as the subject or
object of Cobol verbs (ie. outside of it's defined usage in
READ and START) ?
NOTE:
Both Screen Section (extended Accept/Display)
and
File Sharing/Record Locking
are in the "processor dependent" list of the '02 Standard. This means that a
"fully conforming" compiler need NOT support them. (However, porting from
any X/Open conforming compiler will be EXTREMELY difficult)
Yes, you can say that again !
