Purpose Produces a blank space; no character is printed.

Comment It is not necessary to pad the end of the print line with space characters. The printer automatically fills the line after the line terminator is received.

The Space character code is also used to skip characters for editing and underlining as described on page 63.

Dec Code 95

Purpose Underlines specified character positions.

Comment To underline characters, the print buffer is first loaded with the character line; then the line must be terminated with a Carriage Return code. Spaces are then loaded in the buffer at positions not to be underlined and the underline code inserted in the specific positions to be underlined. Table 15 illustrates underlining.
