I like to nest them like this.  Ron D


mx=Max(rw,Max(Rm28Spm,Max(Rm28Fvg,Max(Rm28Svg,Max(yft25tg,
Max(yt25tg,Max(yt25tg,Max(y2t25tg,Max(y1t50tg,Max(yf6w50g,yf7w50g))))))))));

mn=Min(rw,Min(Rm28Spm,Min(Rm28Fvg,Min(Rm28Svg,Min(yft25tg,
Min(yt25tg,Min(yt25tg,Min(y2t25tg,Min(y1t50tg,Min(yf6w50g,yf7w50g))))))))));

Hello,

Simplest, but repeated code:

x = Max( arr1, arr2 );
x = Max( x, arr3 );
....continued to....
x = Max( x, arr15 );

x now holds maximum of arr1... arr15

The same but this time using loop:

x = Max( arr1, arr2 );
for( n = 3; n <= 15; n++ ) x = Max( x, VarGet("arr"+n) );


Best regards,
