Formats a string and returns it to a variable.

Category
string handling routines
procedure Str(X [: Width [: Decimals ]];
var S);
Description
Str converts 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.
