Stores the signed 32-bit value of an integer
expression at the specified memory location.
Syntax
PUT-LONG ( 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 its region in
not 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 integer value of a constant, field, variable, function,
or expression.
Notes
- For
examples of how to use the PUT-LONG statement, see the PUT-BYTE statement reference
entry.
- 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.
