procedure Val(const S: string; var Result; var Code: integer);
Converts a string to a numeric value.
S is a string-type expression; it must be a sequence of characters that form a signed real number. The Result argument can be an Integer or floating-point variable. Code is zero if the conversion is successful. If the string is invalid, the index of the offending character is stored in Code.
Val does not heed the local settings for the decimal separator.
var s : string;
c,i : integer;
s:='1234';
Val(s,i,c);
//i=1234; //c=0
