The reason for packing is to save space. If you have Char myString[30]=
"ABC", obviously you only need to save 4 bytes ('A', 'B', 'C', '\0'), not
all 30 bytes. If you have a structure containing several strings per
record, and you have many records in your database, the space savings can be
tremendous.

As reported here within the last few days, the max record size is 64K, minus
a few bytes for overhead (31, though possibly the exact number could
change).

The OS uses a UInt16 for record indexes, so that does supply a limit.
