There is no word wrap feature as such since the compiler parses the source code under the assumption that each new line of code is the start of a new statement.
You can however use the concatenation operator (...) to spread a single line of code over multiple lines in the editor. At compile time a pre-processor concatenates these statements into a single line of code before sending it to the compiler.
e.g.
print "Using the concatenation operator I can spread a single line" + ...
" of code over several lines inside " + ...
"the editor"
