[Bug-apl] AP100 problem

[Frederick Pitts]

Gentle people,

        I am having trouble using the AP100 processor.  Code that
worked reliably two to three years ago, no longer works.

        The problem can be replicated (I hope) as follows:

        1) Create a folder named 'Sound'.
        2) Touch a file in 'Sound' named 'playsnd'
        3) Copy the attached 'foobar.apl' into the folder containing
'Sound' and run ./foobar.apl after making sure it has execute
permission.

        The content of foobar.apl is:

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

100 ⎕SVO 'OS' ⋄ 0 ⍴ ⎕DL 1
OS ← ⎕ ← 'ls Sound/*'
OS
OS ← ⎕ ← 'ls Sound/p*'
OS
OS ← ⎕ ← 'ls Sound/pl*'
OS
OS ← ⎕ ← 'ls Sound/pla*'
OS

)OFF

        The output for the above, contained in attached
'foobar.apl.out', is:


1

ls Sound/*
Sound/playsnd
0
ls Sound/p*
Sound/playsnd
0
ls Sound/pl*
Sound/playsnd
0
ls Sound/pla*
sh: -c: line 0: unexpected EOF while looking for matching ``'
sh: -c: line 1: syntax error: unexpected end of file
1

        Why is the last invocation of the AP100 processor failing?  The
error messages reported by 'sh' indicate shell in-line substitution and
end-of-file processing problems.  BTW, I'm running on Fedora 25 where
'sh' is actually a symbolic link to 'bash'.  And the actual application
involves using the AP100 processor to invoke sound apps from an APL
game.

Regards,

Fred
