Stores the 8-byte floating-point value of a
DECIMAL expression at the specified memory location.
Syntax
PUT-DOUBLE ( destination , position ) = expression
|
-
destination
- A variable of type RAW or MEMPTR. If destination is
the Unknown value (?), it remains the Unknown value (?).
If destination is a MEMPTR and has not had its region
allocated (by a SET-SIZE statement or by a Windows dynamic link library
(DLL) or UNIX shared library routine), the AVM generates a run-time
error.
-
position
- An integer value greater than 0 that indicates the byte position
where the AVM stores expression. If position is
less than 1, the AVM generates a run-time error.
For
a RAW destination, if position is
greater than the length of destination, the AVM
increases the length of destination to position plus
the remaining bytes needed to store expression.
The gap between the original destination length
and position is padded with null bytes.
For
a MEMPTR destination, if position is
greater than the length of destination or does
not leave sufficient room to store expression,
the AVM generates a run-time error.
-
expression
- The DECIMAL value of a constant, field, variable, function,
or expression.
Example
For
examples of how to use the PUT-DOUBLE statement, see the PUT-BYTE statement reference entry.
Notes
- This
statement supports byte-swapping only if destination is
a MEMPTR data type. The statement will first examine the byte-order
setting of the MEMPTR and then swap the bytes appropriately while
putting the data into the MEMPTR memory.
