Re: Opening externally-described files as program-described (again)

James,

My experience with program-described files is that the key length in the F-spec is only used at compile time. At run time whatever you use as key is 'thrown at the database manager', which handles it. So you might use a data structure as key and at run time use the appropriate layout.

In your case, because the second key field has a fixed length, it might be interesting to try to switch the key fields. If you then use a 13-digit second key field in the key list, I suspect that at run time only the appropriate number of digits will be used.

Suppose you have a file where you don't know the key length at compile

compile time that it will consist of two zoned decimal fields, with the
first one either 9, 11, or 13 digits, and the second one always 5 digits.

Anybody know how to handle that?
