Re: [open-cobol-list] accept a keystroke?

[Michael]

You may want to explain what your definition of "keystroke" is. The 
Accept verb will read from stdin by default. The From clause will change 
that. The gotcha with the accept verb, is size. For example on my old 
favorite platform (HP3000), when accepting into a ten character variable 
I can type two characters and press return ( carriage control ), and the 
HP Cobol will return the two characters, with the remaining eight 
unchanged. I always initialize the variable before the accept. Other 
Cobol flavors don't do this, they make you enter all ten characters and 
C/R, their maybe other options on the accept verb that will make it work 
like the old HP Cobol did, I donno ;-)

I'm not sure how to do this in OpenCobol, without some intrinsic 
function, but.... Have you looked into opening the stdin file and using 
read/write statements? In the past I've found this to work better, 
because I'd write the applications to accept anything, and then write my 
own editing of whatever was entered, returning the appropriate error 
messages and so on. Gives me more control of how the user interacts with 
the application.
