The colon separates the members of a sequence of algebraic expressions. Its main function is to allow multiple expressions in the branches of an if-then-else statement. Sequences of bracketted algebraic expressions (on the same line) are separated by implicit colons.

Example:

>> if (a==1) then a=a+1 : b=a^2 else c=a+b
>> (1+1) (2+2)
