procedure Str(X [: Width [: Decimals ]]
var S);
Description
Str procedure X to a string representation according to the Width and Decimals formatting parameters. The effect is like a call to Write except the resulting string is stored in S instead of being written to a text file.
X is an integer-type or real-type expression. Width and Decimals are integer-type expressions. S is a string-type variable or a zero-based character array variable if extended syntax is enabled.
就是把一个整形或者实型转化为一个string
var S);

str跟format差不多（前者是过程，后者是函数），我认为format更好用！
如：
var S:string;
Str(5.8:7:2,S)
等价于format('%7.2f',[5.8]);
Str(5:7,S)
等价于format('%7d',[5]);
如：
var S:string;
Str(5.8:7:2,S)
等价于format('%7.2f',[5.8]);
Str(5:7,S)
等价于format('%7d',[5]);
