Erase limit?

I was looking at a platform called "ISTAMP" and its specs said it had a "16KByte memory, 100,000 times erasable"
Does the Basic Stamp have the same·erase limitation?

If you convince yourself that something is impossible before you even try; you are sure to prove yourself right.

All EEPROMs and all flash memory have similar limits. Some memories have limits more like 1,000,000 and some memories have limits more like 1,000 times depending on how they're constructed. The Basic Stamp uses standard EEPROMs which are now quoted by their manufacturer as having limits on the order of 1,000,000 erase/write cycles.
In practice, you're not going to run across this limitation for programming. If you use the EEPROM for data storage (with the READ and WRITE statements), you could run across this. If you wrote to the same location in EEPROM every 50ms which is possible if there's a program bug or poor design, that'd be 360,000 times in a hour. That would exceed the endurance of that location in 15 hours ... very unlikely, but quite possible.
