Program Dimensions

In macro mode FIT2D will not prompt the user for the size of program arrays. By default they will be 1000$\times$1000 pixels. If this is not suitable then their size may be specified on the command line by using the -dim or -dimensions option. (-DIM, -DIMENSIONS, +dim, +dimensions, +DIM, and +DIMENSIONS are equivalent.) 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 X⁵⁸. The -dim option may also be used to avoid being prompted at start-up for the program dimensions.

e.g. The following operating system command line would start FIT2D with program arrays of 500 elements in the X-direction and 700 elements in the Y-direction:

> 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.)
