Description

memsize

25.6

Initial size of memory at startup, in Megawords. You can always change the memory at startup with the -memsize option, or during a Ferret session with the SET MEMORY command. SHOW MEMOR gives the current size of the memory cache.

cmnd_buff_len

2048

Length of the command buffer. You can make long commands more readable using the continuation character backslash \

Number of arguments to go scripts

99

Maximum number of arguments to a go script. Use the syntax ($nn) or $nn in the script. (See Arguments to GO tools)

Length of arguments to go scripts

511

Maximum length in characters of each argument to a go script.

maxvars

2000

Maximum number of all variables defined by SET DATA (including aliases USE and FILE)

max_uvars

2000

Maximum number of all user-defined variables (LET var = )

maxezvars

100

Maximum number of variables that can be read from a single delimited ASCII file, using SET DATA/FORMAT=DELIMITED

maxezfreefmtvars

20

Maximum number of variables that can be read in free format from a single ASCII file, e.g. in SET DATA/EZ/VARIABLES="var1,var2"

maxdsets

100

Maximum number of data sets simultaneously open (as seen through SHOW DATA)

maxstepfiles

5000

Maximum number of files with time step data. These are read via descriptor files. This is a limit on the cumulative sum of all files in all open multi-file data sets.

s_filename

128

Maximum length of the filenames listed within descriptor files.

length of variable names

128

Maximum length of all variable names.

length of label text

2048

Maximum length of labels.

max_grids

500

Maximum number of static grids (grids defined by DEFINE GRID).

max_dyn_grids

1000

Total number of grids that can be defined at any time, static and dynamic. Dynamic grids are created by opening data sets and by implicit regridding operations such as strides (e.g. var[i=1:100:10]), regridding operations between grids of different dimensionality (e.g. temp4d[g=sst]), and external functions that create new grids (e.g. EOF_SPACE(A, F)) .

max_lines

1000

Maximum number of static axes. Static axes are axes defined by DEFINE AXIS

max_dyn_lines

1500

Total number of axes, static and dynamic, thatcan be defined. Dynamic axes are defined by opening data sets and by implicit regridding operations such as strides (e.g. var[i=1:100:10]), regridding operations between grids or axes of different dimensionality (e.g. temp4d[gx=sst]), and external functions that create new grids (e.g. SAMPLEXY(sst, xpts, ypts))

maxlinestore

250000

Maximum number of coordinates in all irregular axes. This is the sum of all the coordinates of irregular axes currently defined via opening files and DEFINE AXIS, and includes storage for the edges of the grid cells defined by these axes. Coordinate storage may be recovered with the CANCEL AXIS command.

abstract_line_dim

20480

Dimension of the default abstract axis for reading ASCII data. To read larger amounts of data, explicitly define an axis or grid.

ef_max_args

9

Maximum number of arguments that may be passed to an external function.

ef_max_work_arrays

9

Maximum number of work arrays defined by an external function for use by that function.

spec_size

250

Maximum number of levels in a spectrum, or palette file (.SPK)

pattern_num

50

Maximum number of patterns defined in a pattern file (.PAT)

year

Years in dates may take values from 0000 to 9999
