The size of the internal program arrays may be specified on the
command line by using the
-dim or -dimensions option. (-DIM, -DIMENSIONS, +dim,
+dimensions, +DIM, and +DIMENSIONS are equivalent.) This avoids
having to edit the DIMENSION OF PROGRAM ARRAYS form, and unless
other options are used starts-up FIT2D with the memory array, but
without variance arrays.
The -dim
option should be immediately followed by the size of the program arrays to
create in the X-direction, and the size of the arrays to create in the
Y-direction separated by an x or an X.
e.g. The following operating system command line would start FIT2D with current data and memory arrays of 500 elements in the X-direction and 700 elements in the Y-direction, but no variance arrays:
> fit2d -dim500x700
(The DIMENSIONS command may be used within a macro as an alternative method of changing the size of program arrays from the default values.)
