Plus42 algebraic expressions update

[Vincent Weber]

Oh and one more thing: the 27S allows to enter the PRINT menu in the equation editor, in both list mode et editing mode. This is most useful to print both the equation list and the current equation (especially because we only have one line to edit). Now I understand the whole equation list could be printer by printing the EQNS variable, but to print the current equation there is no easy solution. The 27S has a dedicated PRT key that helps, which the 42S doesn't have. Any idea ?

Cheers
