GT.M actually has three options with respect to null subscripts:

  - prohibit null subscripts - error to read as well as set
  - permit null subscripts - OK to read as well as set
  - permit existing - OK to read, error to set

Orthogonal to the above are two options for collating null subscripts:

  - between numerics and strings (traditional GT.M method)
  - before numerics (M standard method)

So...without this option, the following wouldn't be an error??

BAY>S ^TMP($J,"")=""

S ^TMP($J,"")=""
^
<SUBSCRIPT>
BAY> 

(Yes, I know, this is Cache.)
