So you can save the result of )HOST in a variable if you use
⍎. To feed it a var, I would try something like:
]BOXING 2
⎕←FILE←⍎')HOST cat test.txt'
hello, world This file was written in my $HOME directory. 0
⍴FILE
5
FILE
.→-----------. .⊖. .→-------------------------------------------. .⊖. .→-.
|hello, world| | | |This file was written in my $HOME directory.| | | |0 |
'------------' '-' '--------------------------------------------' '-' '--'
Several things to note here. First of all, linefeeds / carriage returns / whatever
you want to call them in the file I read seemed to mark nested array ends, and
it seems that those LFs were lost. I don’t know how GNU APL handles LF chars,
so I would recommend you either keep the array boxed or disclose it like I did
in the first example (∊ enlisting it simply catenated all the lines together, as
the LFs were represented by ⊂⍬, boxed empty vectors).
Second, if you’re reading this Jürgen, note that even though ]BOXING was set
to 2, the result of ⎕←FILE is not boxed.
IMHO this is potentially the cleanest way to read a file. I have no idea how to tie
files and stuff like that.
Best of luck,

Hi Bug-apl,
Currently, at a point in my code I do something like this:
⍝assume the variable 'yadda' exists and is correctly formed, as well as the read_file function
success←yadda ⎕fio[7] tie← 'wr'⎕FIO[3] "yadda.file"
yadda_new← read_file "yadda.file.new"
⍝end of code
My question is: is there either 1. a way to feed )host a variable (I don't think that is possible) or 2. a better way to implement this task in its entirety. I find it a small nuisance that I have to write and then read a file in my code to access non-APL stuff for processing.
