1 If one or more fields allow null values, the limit is reduced by one to 254 fields.
2 Limited by memory and available file handles. .cdx files use only one file handle.
3 If the collating sequence is set to MACHINE, each character uses one byte. If the collating sequence is not set to MACHINE, each character uses two bytes. If the indexed field supports null values, one additional byte is used in the index key. Note that non-machine indexes are always compact.
4 A program module is one procedure. A program or application can contain an unlimited number of program modules.

>>Would like to know some of the limits of VFP.
>>
>>1. How many memory variables can we have?
>>2. How big can a table get ? (in terms or records)
>>3. How many filed can one have in a table ?
>>4. How many indexes can we attache to a table ?
>>5. How many tables can we have in a database ?
>>
>>I would like more questions answered, but if someone can point me in the right direction to find these answers that would be really helpfull.
