f - parse a 32-bit floating point number (4 bytes)
c - parse an 8-bit signed number (1 byte)
C - parse an 8-bit unsigned number (1 byte)
n - parse a 16-bit signed number (2 bytes)
N - parse a 16-bit unsigned number (2 bytes)
m - parse a 24-bit signed number (3 bytes)
M - parse a 24-bit unsigned number (3 bytes)
l - parse a 32-bit signed number (4 bytes)
L - parse a 32-bit unsigned number (4 bytes)
There is an optional single digit d which may follow any of the numeric
fields, which indicates that after the field has been parsed out, the
resulting value is to be divided by 10^d. Thus the 16-bit field 0xFFC6
would be interpreted with the format specifier ‘n3’ as the number
-0.058.
The subsequent lines in the erec layout response describe the appearance
of the full panel. The full instrument panel as it appears on the screen
has two columns of lines. Each line is composed of three major
components: (1) a text field, (2) a value field, and (3) a button. None
of these three components is required. The text field contains statically
displayed text.
The value field displays values which are parsed out of the response to
a erec command. It also displays, though background changes, alarm
status. The button, when pressed, triggers input from either a dialog box
or a selection list. There are five kinds of buttons, B, I, L, T, and N.
Each line in the layout string corresponds to one line on the display.
The layout string describes each of the three major fields as well as
translation mechanisms and corresponding commands.
The first field in the layout string is the text. It is delimited by a ‘:’. The
string up to the first ‘:’ will be read and inserted in the text field of the
line.
This is followed by a possible string enclosed in quotes that is used to
place a string into the value field.
The value source, which is the item (or word) number in the DATA/
EREC response, appears next. This is followed by an optional bitfield
designator. The datum identified by the value source can be printed
as a string ‘s’, hexadecimal ‘x’, decimal ‘d’, floating point ‘f’, or binary
‘b’ number. Typically, bitfield extractions are only done for decimal or
hexadecimal numbers.
