Will,

Thanks, I ran your sample code and it works like I found sysgetkey to
function. "Yes", it doesn't wait for the ENTER key to be pressed,
but it does "pause and wait" for a key to be pressed. Sorry, but
this isn't what I'm looking for. I need to poll the keyboard for a possible
key-press, and not pause to wait for one.

Below is some basic code of the function that I need to implement in rexx:



loop:

   rem
   rem Code is executed here, between the lable "loop" and the
following "if"
   rem statement. Basically, the code is run within a loop, over and over, 
  rem until a user terminates it by "touching" the keyboard...
   rem

   a$=inkey$ : if a$="" then goto loop

   rem
   rem if a$ comes back with a value, then a user desires to terminate the 
   rem loop.
   rem

   rem
   rem the program terminates
   rem

   end



All possible combinations of rexx that I have tried, I have not found a
pure rexx solution to the above "inkey" function. Craig Morrison,
201/60, has taken the time to provide me with an "inkey solution"
in the form of a C routine compiled into a rexx loadable .dll. It works
beautifully, but it's something that I have to include in whatever rexx
program that I write, that would need to poll the keyboard. From what I
have found in my rexx experimentaion, the above "inkey" function
can't be done in rexx.

Shame too.

Any more suggestions?
