Contents
Zbex gives you two commands which relate to directories: getdir and createdir. In addition, you can read the contents of a directory by opening it as a file.
getdir
The getdir statement will provide you with the path of the current directory. There is no way with Zbex to change the current directory. The following example will open the current directory, read its contents, and display them on the screen.
Program
---------------------
str curdir.80,rec.80
getdir curdir
open [1,1] curdir
loop
getf [1] rec
putc ~rec
repeat
run
Execution
-------------------------------------

createdir
The createdir statement lets you create a new directory. The path to the new directory must already exist (you can create it, one sub-directory at a time). Zbex does not provide you with a means of removing directories (or removing files, either). The following example will create a new directory in the current directory.
Program
---------------------
str newdir.80,curdir.80
str rec.80,temp.80
getdir curdir
B:
putc Name of new directory?
getc newdir
temp = ucs(newdir) /* for comparing with current names
Make sure that this directory doesn't already exist
open [1,1] curdir
loop
getf [1] rec
if rec{1} = " " /* no more entries in directory
goto A
end
if rec{18} = ">" /* looking for sub-directories
if rec con " "
rec = rec{1,mpt-1} /* keep only the name
end
if rec = temp
putc This directory already exists
close [1] /* must close [1] so we can open it an
goto B
end
end
repeat
A:
close [1]
Directory doesn't exist; try to create it.
newdir = curdir // "/" // newdir
createdir newdir
putc ~newdir created
run
Execution
-------------------------------------
Name of new directory?
specs
This directory already exists
Name of new directory?
