Use a function like this one to execute a host command and get the result into
a variable.
ps: still debugging this one.

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"
)host ./shellscript.sh <http://shellscript.sh> yadda.file yadda.file.new
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.
