SYNOPSIS

function visible(input) result(output)

    character(len=*),intent(in)  :: input
    character(len=:),allocatable :: output

DESCRIPTION

visible(3f) expands characters to commonly used sequences used to represent the characters as control sequences or meta-control sequences.

EXAMPLES

Sample Program:

    program demo_visible
    use M_strings, only : visible
    integer :: i
       do i=0,255
          write(*,’(i0,1x,a)’)i,visible(char(i))
       enddo
    end program demo_visible

BUGS

The expansion is not reversible, as input sequences such as "M-" or "^a" will look like expanded sequences.
