Hi,
You are displaying long-nbr as a character string, not as a number,
so, "@4" is probably 0x40340000, which, according to my calculations
is the floating point representation of 7.
HTH
FYI,
Here is a bit of Cobol to to convert an Integer to a Real for use in
"pause".
(The code doesnt handle negative numbers)
move 5 to IntegerValue
call "IntegerToReal" using IntegerValue giving RealValue
call "PAUSE" using RealValue
where both IntegerValue and RealValue are 'binary pic s9(9)'

Here's my test program. I'm just wondering what the @4 means when it
displays the value of long-nbr - which you say is an address. I'd have
expected some large value pointing to an area of memory like I'd get in
