RAW ( field[ , position[ , length]] ) = expression
field
The field in which you want to store expression.
position
An integer expression that indicates the position in field where
you want to store expression. The default for position is 1.
length
An integer expression that indicates the number of positions
you want to replace in field. If you do not use
the length argument, RAW puts expression into field from position to
end. ABL treats variable-length fields and fixed-length fields differently.
See the Notes section for more information.
expression
A function or variable name that returns data and results in
the bytes that you want to store in field.
Notes
In
a variable length field, if (position +length -1)
is greater than the length of field, the AVM
pads the field with nulls before it performs the replacement.
In a fixed length field, if (position +length -1)
is greater than the length of field, the AVM
returns a run-time error. If (position + length -1)
is less then the length of field, the AVM pads
the field with nulls so that it remains the same size.
If position, length, or expression is
equal to the Unknown value (?), then field becomes
the Unknown value (?).
If position is less than 1, or length is
less than 0, the AVM generates a run-time error.
