Parameters
filename
in
required
the filename
varname
in
required
the name of the variable to be written
z2d
in
required
the variable (2D array) to be written
Keywords
I2
I4
I8
R4
to change the default format (R8) of the data to be written.
APPEND
to open the file with the file pointer at the end of the file, ready for
data to be appended.
RECSIZE
define the size of the full data array to be written. Usefull when
you want to save memory and write the data in several write_oasis
instructions. see example
TEMPORARY
activate undefine z2d when yo write it (to save memory) -> z2d will
be lost once write_oasis is returning.
HEADER
activate to write the header ("character*8" contained in varname)
before writting the data. Used when recsize is defined and /= 0, see example
ENDING
activate when you write the last part of the data. Used when recsize
is defined and /= 0, see example
POSITION
specify the position (in byte) at which you want to write the
data. Used when recsize is defined and /= 0, see example
Examples
write_oasis, fa2of, 'WEIGHTS5', weig
or in several call so save memory
ysz = 100L
recsz8 = 16L * jpio * jpjo * 8L
FOR i = 0L, jpjo-1L, ysz DO BEGIN
ii = (i+ysz-1L) < (jpjo-1L)
position = (4L + 8L + 4L + 4L)*(i NE 0) + 16L * jpio * i * 8L
weig = ....
write_oasis, fa2ou, 'WEIGHTS3', temporary(weig), /temporary, append = i NE 0, header = i EQ 0 $
, ending = ii EQ jpjo-1, recsize = recsz8, position = position
