- Detached Headers:
- On occasion a file with binary data may be provided that users wish to
"import" into a Midas framework.
- This is done through the use of a Detached Header.
- A detached header allows the Midas Blue header to be stored in a
separate file from the data.
- This file looks like a normal Blue file (with a
.tmp or
a .prm extension), except that it has no data section
(the Extended Header immediately follows the Main Header) and
it has the "detached" flag set in the Main Header.
- The binary data is then stored in a corresponding file with a
.det ("detached data") extension.
- In this case there are two files, the Blue File header
(
<filename>.tmp or <filename>.prm )
and the detached data (<filename>.det ).
- (Some Midas frameworks allow the file names and
extensions for the detached file to be overridden through the use
of qualifiers.)
- When a Midas framework sees a Blue File with the detached flag set it
knows to look there for the main header and extended header and to
look in the
.det file for the data.
- In both X-Midas and NeXtMidas a detached header can be created using the
HEADERMOD command.
