0002 2 undefined floating point Size
0003 3 undefined integer Age%
0201 513 string variable Name$=”Smith”
0202 514 floating point number Size=1.85
0203 515 integer number Age%=38
0301 769 string array DIM a$(10,20)
0302 770 floating point array DIM a(221)
0303 771 integer array DIM a%(10000)
0400 1024 BASIC PROCedure DEFine PROCedure QUIT
0501 1281 BASIC string FuNction DEFine FuNction Who$
0502 1282 BASIC floating point FuNction DEFine FuNction Tm(day)
0503 1283 BASIC integer FuNction DEFine FuNction Age%
0602 1538 REPeat loop name REPeat forever
0702 1794 FOR loop name FOR i=1 TO n
0800 2048 machine code procedure RUN, ED, NEW
0900 2304 machine code function QDOS$, VER$, FILL$


Parameters must be given in quotes if you want to find out the type of the actual name, eg:


If quote marks are not used, then the value of the parameter is passed instead - eg:


will not return the type of name$ but the type of RUN.
