Sharp BASIC anomaly

[polbit]

I stumbled upon something a bit strange playing around with few of my Sharp pockets.

The following code:

Code:

10 P$ = "PASSWORD"
20 IF P$ = "PASSWORD" THEN PRINT "CORRECT"

Executes correctly on PC-1500, however it fails on both EL-5500II and PC-G850VS. It appears the later two only recognize first seven characters in a string, despite being newer, so only the following works:

Code:

10 P$ = "PASSWORD"
20 IF P$ = "PASSWOR" THEN PRINT "CORRECT"

This might be a well-known fact, but figured I'd share as I found it interesting...
