Synopsis

print is undoable, queryable, and editable.

The print command displays its argument in the Script Editor (or in standard output in batch mode). If the argument is not a string it is converted to one.

Float, vector, and matrix arguments are always printed with C format code %.10g.
Vectors are formatted with spaces separating components.
Matrices are formatted with commas separating elements of a row, and each row begins on a new line. They are surrounded by << and >>.
Arrays are formatted with each element on a new line.

New lines are not automatically appended to output.

Return value

None

MEL examples

// To print a scalar (int, float, string):

$i=42;
print $i;
// 42

$f=3.14159;
print $f;
// 3.14159

$s="Hello There";
print $s;
// Hello There

// To print a vector:

vector $v;
$v=<<1.2, 2.3, 3.4>>;
print $v;
// 1.2 2.3 3.4

// To print a matrix:

matrix $m[2][3]=<<3.14159, 2.3456781232131, 1; 4.561234586903, 5.342143, 42>>;
print $m;
// << 3.14159, 2.345678123, 1;
//    4.561234587, 5.342143, 42 >>

// To print an array:

string $a[];
$a=`ls -lights`;
print $a;
// ambientLightShape1
// directionalLightShape1
// pointLightShape1
// pointLightShape2

// To construct a string argument for the print command, use the
// + operator to concatenate elements of that string.
// Note that parentheses are required around expressions which
// form a single command argument.

print ("$i="+ $i + ", $f="+$f+"\n");
// $i=42, $f=3.14159
