Descriptor types

The types of descriptors are the following:


Boolean
A descriptor of type Boolean must evaluate to either TRUE or FALSE.

color
A descriptor of type color must evaluate to one of the following strings: black, blue, green, cyan, red, magenta, yellow, or white, or one you define using setcolor(1fmli).

command
A descriptor of type command must evaluate to an FMLI command, such as open, nop, exit.

integer
A descriptor of type integer must evaluate to an integer value.

layout
A descriptor of type layout (there is only one, slk_layout) must evaluate to one of only two values: either 3-2-3 or 4-4.

null
A descriptor of type null exists only to get the side effect of a backquoted expression. Its value is ignored.

position
A descriptor of type position must evaluate to an integer value or one of the strings any, center, current, or distinct.

string
A descriptor of type string must evaluate to a sequence of characters.


NOTE: If the integer value assigned to a descriptor that determines the offset of a frame or any of its components is greater than the boundaries of the screen work area, the frame will not be posted. The begrow and begcol descriptors are the exceptions to this. They default to any.
