Re: [Bug-apl] CGI script prints instead of executing when FILE_IO is copied in

Thanks Jürgen, I will try that. I think I got the idea of 0 0 ⍎')COPY' from your example, and didn't really understand what it is really doing, besides not printing the result.

Hi Alex,

on my machine the behavior is the same when FILE_IO is )COPYd or not )COPYed.
Looking at the script I would say that printing the page should be the expected behavior.

Maybe the )COPY of FILE_IO or HTML fails (and the error is hidden due to 0 0⍴⍎).

You could als try )SI instead of )OFF,  )COPY instead of 0 0⍴⍎')COPY', and remove --script to see
more of what's happening.

A frequent difference between CGI-scripts run from the command line or from a web server is environment
variables, PWD, and the like. Since you use a relative path in )COPY 5 HTML the result may depend on
such things. To make things explicit always use absolute paths and full file extensions.

Hi Bug-APL,

It appears that this script works if FILE_IO is not copied in. When the FILE_IO is copied in, it appears that the cgi script runs but prints the HTML to the page. Is FILE_IO 's existence in the program make the script run under different conditions? (or is it possible there is something wrong in the non-APL part of the CGI interaction, in which case I'll troubleshoot elsewhere.)

#!/usr/local/bin/apl --script --

0 0 ⍴ ⍎')COPY /usr/local/lib/apl/wslib5/FILE_IO.apl'

0 0 ⍴ ⍎')COPY 5 HTML'
