Question about backspace command in gcc-g77-3.0.2

[Youngjean Jung <yjjung at newton dot me dot berkeley dot edu>]

  Dear g77 developer :

I downloaded gcc3.0.2 and am using g77. According the following 
statement of yours,

g77 doesn't support FORM='PRINT' or an equivalent to translate the 
traditional `carriage control' characters in column 1 of output to use 
backspaces, carriage returns and the like. However programs exist to 
translate them in output files (or standard output). These are typically 
called either fpr or asa. You can get a version of asa from 
ftp://sunsite.unc.edu/pub/Linux/devel/lang/fortran for GNU systems which 
will probably build easily on other systems. Alternatively, fpr is in 
BSD distributions in various archive sites.

backspace command doesn't work. Also I checked it didn't work. But this 
makes me feel really bad because I need the backspace command during 
execution. After execution, asa may help. But the backspace command is 
absolutely necessary to control files during execution. Is there any 
plan to support the backspace command?

I would appreciate you if you inform me of solving this big trouble.

Sincerely,

Youngjean Jung
