Re: [Bug-apl] working with )HOST

[Christian Robert]

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


      ∇Execute[⎕]∇
    ∇
[0]   z←Execute cmd;⎕io;fh
[1]   ⎕io←0
[2]   fh ← ⎕FIO[24] cmd
[3]   z←⎕av[⎕fio [8] fh]
[4]  Loop: →(0≠⎕FIO[10] fh)/Fini
[5]   z←z,⎕av[⎕fio [8] fh]
[6]   →Loop
[7]  Fini: ⎕FIO[25] fh
[8]   ⊃⊃z
    ∇
