Ya,

Wrap parentheses around each object which you wish to print if
the object is not a named variable, vector, or matrix.  That is,
write

print (1) (2) (-3);

That will resolve just fine.  The use of parenthese is required
for printing objects/values which are created during execution of
the PRINT statement.
