The syntax seems to be quite off... To start off, the '+' suggests you want to add the string to something. Because you did not specify what to add the string to, you get part of your error. The 'TO' command is only used in FOR loops, and labels ('@') are only used with commands like GOTO and RESTORE. The syntax for PRINT is simply:
PRINT string or number or variable[,...]
