Is this a bug or a feature?

Mathcad shows this as a pread sheet [array,NOT vector.

Elsid,
Neither a bug, nor a feature. Your Mathcad snippet is NOT a spread sheet.
A spread sheet is typical of Excel, it has col/row identifiers.

Mathcad shows a display w/o col/row identifiers. It has many interesting
features that Smath does not have, mostly as local exploder for plotting.
You can plot erf(,) vs x directly. If you assign the project like we do
in Smath, Mathcad will display col/row in gray and you will plot row/col.

So, Mathcad display [not an assigned creation] ... NO col/row identifiers.
A Mathcad creation, i.e: an assigned creation ... col/row identifiers.

Many Mathcad Collabs asked about this distinction, I had a copy/paste reply.

All that explained, it would a great feature Smath distinguish a display by
some kind of non printable distinctive invention . For instance a damier
of little yellow/white squares [yellow lovely default Smath 255,255,225]

Now check this (it is a part of a bigger calculation). If I use equal sign after assignment I get a matrix. If I try to get result again in next line, it magically renders to scalar.

Please: next time, attach the *.sm document
