I am submitting another utility for batch files, bat-cd, for the
INFO-IBMPC library.  This program allows a batch file to change
directories (just like the CD command), but to read the new directory
from the "standard input file" instead of the command line.

The command:

        bat-cd          reads new directory from keyboard
        bat-cd < file   reads new directory from "file"
        bat-cd <file >nul  no display of new dir name when changing

You can use the directory changer to change back to the directory a
batch file started out with, such as when doing a spelling correction
or fancy font printing.
   .
   .   (your batch file to do fancy font from any directory)
   .
   echo off
   cd > \bin\bat\starting.dir           saves initial directory
   copy %1 \fancyfnt\temp/v             make file local to pfont dir
   cd \fancyfnt                         go to pfont dir
   pfont +fi temp +fo romn12 (etc.)     do printing
   del temp                             get rid of local file copy
   bat-cd <\bin\bat\starting.dir >nul   return to user's directory
   echo on

If you were going to, for example, a speller directory, which made
changes to the file, then you would copy the local file back before
changing directories back:

   echo off
   cd >\bin\bat\starting.dir            save initial directory
   copy %1 \speller\temp.txt/v          make your file local
   cd \speller
   spellit temp.txt
   bat-cd <\bin\bat\starting.dir >nul   change back to user's dir
   copy \speller\temp.txt %1/v          copy spelling corrected file
   del \speller\temp.txt                   back & delete other copy
   echo on

Note that the new input is read as a single line, without any prompt,
followed by a carriage return.  If the input is not a valid directory,
then the message "path not found" is placed on the standard output
file (console, but redirectable if one wishes).
