Convert every number in a list or matrix to strings

Hi everyone, just out of curiosity, I wonder if there is a way to convert every numbers in a list to strings?

For eg, I have a list:

listsss = {1, 4, 56, 72, 8, 9, 10};

and I want to convert them into:

listsss = {"1", "4", "56", "72", "8", "9", "10"};

Is there any way to do it by JSL? Any comments will be appreciated. Thank you!

L = {10, 200, 3000};
For( i = 1, i <= N Items( L ), i += 1,
	L[i] = Char( L[i] )
);
Show( L );

L = {"10", "200", "3000"};

In JMP 16 you can use Transform Each() like this

L = {10, 200, 3000};
L = Transform Each( {v}, L, Char( v ) );
Show( L );

By default the output container matches the input container. You can use output(...) to control it:

L = [10, 200, 3000]; // actually, an array or matrix, not a list
L = Transform Each( {v}, L, output( "list" ), Char( v ) );
Show( L ); // L = {"10", "200", "3000"};

For huge lists and matrices, this will perform a little better than the plain for loop.
