A string is just an array of byte values that happen to be characters and, by convention, end with a zero byte. You can't directly assign strings, but you can copy them with BYTEMOVE (look in the Propeller manual for details). Here's a simple example:

VAR byte helloStr[noparse][[/noparse] 9 ]

PUB main
   BYTEMOVE(helloStr,6,string("hello"))   ' copy the string constant plus its zero byte
   if strsize(@helloStr) <> 5                    ' make sure the string is 5 characters
      ' do something
   if helloStr[noparse][[/noparse] 0 ] == "h"                          ' if so, check the first character
      ' do something
   if strcomp(@helloStr,string("hello"))     ' you can compare strings for equality this way
      ' do something

@Mike Green and marcla

The

BYTEMOVE(helloStr,6,string("hello"))

should be

BYTEMOVE(@helloStr,string("hello"),6)
