In wcalc how can I do something like-> 1+2 = 3-> X+1 = 4where X equals the result of the last calculation (that is 3)?
How to use the result from last calculation in a new calculation in wcalc?
shell;calculator
The special variable a contains the result of the last answer-> 1 + 2 = 3-> a + 5 = 8-> From the wcalc README fileSome special notes about variables - two things are reserved: a - this variable represents the last answer, and may be used in expressions. q - this variable is reserved in the command-line version (it means quit), and cannot be used in expressions. Also, built-in constants cannot be re-defined, although they are  treated as variables in all other cases.
