Re: [ferret_users] header



Hi -
Here  are some ideas to get you started. I'll let you work out the whole thing.
! Here's how to list a string, without quotes, and without a
! header for a string variable


LIST/CLOBBER/FILE=out.dat/NOHEAD/FORMAT="(A)" dsaa

! Now list the number of points in the i and j direction

LET ni= `var,RETURN=isize`
LET nj = `var,RETURN=jsize`
LIST/APPEND/FILE=out.dat/NOHEADER/FORMAT=(2f6.0) ni, nj

LET xmin = `var,RETURN=xstart`
...
and so on. You can LIST/NOHEADER/FORMAT= to write the rest of the lines you want. 

You can control the formatting of the lines by defining a string variable with the exact contents you want for the format of each line, so for example, instead of the block above with ni and nj,
LET ninj =   "    Nx = `var,RETURN=isize`,     Ny = `var,RETURN=jsize` "
LIST/APPEND/FILE=out.dat/NOHEADER/FORMAT="(A)" ninj
