gestione directory

visualizzare directory corrente,eventualmente assegnare nuova directory,salvare file,richiamare file (txt,dat)
(usando le icone del menù oppure inserendo codice comando)

ipotesi:creata cartella personale in C:\progragnu\
sottocartelle in progragnu per file tipo txt, plt, dat :esetxt, eseplt, esedat
(non necessario avere più cartelle:basterebbe progragnu)
esempi indirizzamenti con icone (non inserire apici)

OPEN.....C:\progragnu\esetxt\..............C:\progragnu\esetxt\file.txt
SAVE.....C:\progragnu\esetxt\file.txt

esempi indirizzameti diretti da codice (inserire apici)
LOAD.....'C:\progragnu\esetxt\file.txt'
SAVE....'C:\progragnu\eseplt\file.plt'

uso di icone SAVE,OPEN o FILE

con inserimento percorso da codice

# scrivere file tipo dati prova2.dat
# regitrarlo come prova2.dat
# richiamarlo con PLOT e prova2.dat
# registrarlo con SAVE e prova2.plt
# richiamarlo con OPEN e prova2.plt

# fine file

richiamare file.txt con NOTES-FILE-APRI per eventuali modifiche,correzioni:poi FILE-SALVA

# esempio file scritto con notes
# registrato con SAVE c:\progragnu\esetxt\prova1.txt
# richiamato con LOAD c:\progragnu\esetxt\prova1.txt
# registrato con SAVE c:\provagnu\eseplt\prova1.plt
# richiamato con LOAD c:\provagnu\eseplt\prova1.plt
# visualizzato codice prova1.plt con NOTES :FILE..APRI...
# visualizzato listato prova1.txt con NOTES:FILE..APRI...
#

plot sin(x),cos(x),x

# fine listato

richiamare file.plt con NOTES-FILE-APRI per vedere codice
