To use
DDE in SAS, issue a FILENAME statement with the following syntax:
FILENAME fileref DDE 'DDE-triplet' <DDE-options>;
where:
DDE-options
can be any of the following:
LRECL=record-length
specifies the record
length (in bytes). Under Windows, the default is 32767. The value
of record-length can range
from 1 to 1,073,741,823 (1 gigabyte).
RECFM=record-format
controls the record
format. The following values are valid under Windows:
F |
indicates fixed format. |
N |
indicates binary format and causes the file to be
treated as a byte stream. If LRECL is not specified, by default SAS
reads 32767 bytes at a time from the file.
|
P |
indicates print format. |
V|D |
indicates variable format. This is the default. |
CAUTION:
Use caution
when using DDE with data values that are blank or missing.
