Re: [Bug-apl] AP100 problem

[Frederick Pitts]

enztec,

In a terminal interactive bash shell

  /bin/ls /apl/ap100/Sound/pl*
  /bin/ls /apl/ap100/Sound/pla*

and in an apl interactive interpreter session 

  )host /bin/ls /apl/ap100/Sound/pl*
  )host /bin/ls /apl/ap100/Sound/pla*

produce the correct results.

And I'm unaware of a glob length setting.

Later,
