aString asText
Last updated at 11:52 am UTC on 19 July 2022
Instances of class String have no attributes associated with them.

With #asText you get a Text instance to which TextAttributes may be added.

 aText := aString asText

Then with 

 aText asMorph

you may get a TextMorph.

Thus

 aString asText asMorph

gives a TextMorph instance.

Whereas a
 aString asMorph

gives a StringMorph instance.

Thus both class String and class Text implement #asMorph but with different resulting morphs.
