Writing on the same line in FORTRAN -

-

in fortran, each time 1 uses write new line produced. in order control working of program being executed, write on screen current value of variable, on same line (erasing previous value , starting @ beginning of line). is, like

 1    continue       "update value of a"       write(*,*)       backspace "screen"       goto 1

something write(*,*,advance='no') (incorrect anyway) not quite need: write values of a 1 after on long line.

a trick shown want follows

do l=1,lmax    ...update a...    write(*,'(1a1,<type>,$)') char(13), enddo

where <type> format specifier a (i.e., i0 integer).

the key char(13), carriage return, , $ in format descriptor. don't know if there name $, know works displaying on screen--for output file a on each line.
