Subj: Directory TREE for HP48SX
Date: Sat Oct 06 1990 05:25
TREE
The following program will create a graphic that is the directory
tree of the 48. That is, an indented list of all directories in
the system:
HOME [0]
SYS [1]
ELECT [2]
CIR1 [3]
CIR2 [3]
NMBR [2]
BI [3]
LSQ [3]
THERM [4]
Y44006 [5]
Y44203 [5]
FIN [2]
And so on.
When the graphic is displayed, the UP and DOWN arrows are used to
navigate the LCD. Preceding the UP/DOWN keys with the blue arrow
moves to the top or the bottom of the list respectively. The
display may be printed by switching to the normal GRAPH mode
(with the orange arrow followed by the LEFT key), pressing STO,
and then using PR1 to print the GROB in level 1.
The program is written in two sections. Section 1 recursively
builds a list-object of directories that are tagged to reflect
their system levels. The bracketed numbers in the above example
represent the directories' system levels; they are not displayed.
Section 2 of the program translates the list-object into a graph-
ic display.
I would like to acknowledge that much of the inspiration for the
graphic section of this program was provided by Kevin Jessup's
EDIR program.
