Quote:There is no longer the ability to use multi-statement expressions, with each expression separated with a colon. Even when it was available, (1) storing results immediately terminated the expression (forcing the use of Ans and when available, PreAns to make using results in the next part possible), and (2) when replayed, the statement was broken up into separate parts.

This is true, but you use multistatement in wrong way. And you do not checked the linked video Just few minutes and you can see multistatement how efficient. AND I'm sure if you try, you will surprised how easy to expand the possibilities and add an IF/THEN structure for a non-programmable calculator.

Just try it:

Code:

Type in C=A+B:D=C/2
press [CALC]
Type something for A and B, eg. 7 [EXE] and 3 [EXE], then you can see value of C, then [EXE] again, you can see value of D.
At this point, you can edit the WHOLE expression, just press [left] and you will get the original C=A+B:D=C/2 multistatement for edit.
