This function is OBSOLESCENT and exists only for backward
compatibility with old CoCoA code.
It returns a string containing just a newline; in CoCoA-5 it is
simpler to write
\n
.
Example
/**/ str1 := "Line 1" + NewLine() + "Line 2"; --> old CoCoA-4 way
/**/ str2 := "Line 1\nLine 2"; --> more compact in CoCoA-5
/**/ str1 = str2;
True
/**/ Print str2;
Line 1
