Adding an object to a string: +

### 6.3.12 Adding an object to a string: +

The ’+’ command can be used like cat (see Section 6.3.11), and the + operator is the infixed version. (See Section 6.16.1 for other uses of + and ’+’.)

- ’+’ takes one argument:
  seq, a sequence of objects, at least one of which is a string.
- ’+’(seq) returns the concatenation of the string representations of the objects in seq.

Warning.
+ is infixed and ’+’ is prefixed.

Examples.

- Input:
  ’+’("abcd",3,"d")
  or:
  "abcd"+3+"d"
  Output:

  "abcd3d"

- Input:
  c:=5
  then:
  "abcd"+c+"d"
  or:
  ’+’("abcd",c,"d")
  Output:

  "abcd5d"
