FXBPARSE

FXBPARSE

Name


FXBPARSE

Purpose


Parse the binary table extension header.

Explanation


Parses the binary table extension header, and store the information
about the format of the binary table in the FXBINTABLE common
block--called from FXBCREATE and FXBOPEN.

Use


FXBPARSE, ILUN, UNIT, HEADER

Inputs


ILUN = Index into the arrays in the FXBINTABLE common block.
HEADER = FITS binary table extension header.
  Opt. Inputs :
None.

Outputs


None.
  Opt. Outputs:
None.

Keywords


NO_TDIM = If set, then any TDIMn keywords found in the header are
ignored.
ERRMSG = If defined and passed, then any error messages will be
returned to the user in this parameter rather than
depending on the MESSAGE routine in IDL. If no errors are
encountered, then a null string is returned. In order to
use this feature, ERRMSG must be defined first, e.g.
ERRMSG = ''
FXBPARSE, ERRMSG=ERRMSG, ...
IF ERRMSG NE '' THEN ...

Calls


FXBFIND, FXBTDIM, FXBTFORM, FXPAR
  Common :
Uses common block FXBINTABLE--see "fxbintable.pro" for more
information.

Restrictions


None.

Side Effects


Any TDIMn keywords found for bit arrays (format 'X') are ignored, since
the dimensions would refer to bits, not bytes.
