Tech Notes

Swap doesn't always (...swap)

It is OK to use FBII's well worn pseudo records in the cube (FB^3), but you need to keep in mind that some of the old limitations that were inherent in such a structure still remain. For instance, FBII stored a type (but not a size) for its string records.

DIM RECORD myRecord
 DIM 26 myString$               // This won't work!
 DIM myOtherVarIsAVolvo%
DIM END RECORD .myRecordSize

DIM myArray.myRecordSize(100)

SWAP myArray.myString$(1),myArray.myString$(2)

If you are going to use SWAP, possible solutions are:

DIM all strings in old records without a size limit so that they are 256 bytes long.

Handle the SWAP manually by transferring data into another variable during the process.

Use true records instead of the old pseudo records.
