If I have the following in a buffer
2001111 +03
and I have the cursor at the number 2

then in command mode I write the following

OI() EV() OI(clear)

I was expecting the buffer to change to the following
2001114
2001111 +03

but nothing is happening

in fact if I have just
EV() I was expecting 2001114 to be returned in command mode but that doesn't happen either.

What about:

#1=num_eval()
num_ins(#1,NOCR) ?

For one thing, "ev()" is not a valid command.
Also, Fritz's way is cleaner.

The command EV() doesn't exist.
You are meaning Num_Eval() or NE(), right?

So it should read:
OI() .NE() OI(clear)

Please note the dot in front of NE()!
It prints the result to the console and then via OI() into the buffer.

Yeah, sorry about that Ted, twas late at night:-(

what I meant to say was that when the buffer cursor position is at a numeric expression then the following does not work
oi() ne() oi(clear)

Aahhh.......ohhhhhhh ...wooooow!!!... I like that trick with the dot:-)

I can see though that Fritz's way is better for me because I don't wish to insert a CR and it allows nocr to be used.


Thanks Christian

Steve:

You are going to get strange results when you try to read something that you are modifying at the same time. That is why Fritz's method was cleaner.
