Introduction 1-5
Any ACL error causes the System to ignore all characters until the next semicolon ";" or
letter "A" through "Z".
Parameter Types
Some commands, for example ES and OU, have string parameters. The syntax of string
parameters is described with those commands in Chapter 3.
Numeric parameters fall into two categories: fractional and whole numbers. Fractional
parameters typically can be in the range -32768.0000 through +32767.9999. Only the first
four digits after the decimal point are significant; if more are given, the excess digits are
ignored. If no sign ("+" or "-") is given the parameter is assumed to be positive.
Whole number parameters are typically treated as integers in the range 0 through 65535. If
there are digits after the decimal point, the number is rounded to the nearest integer. Values
in the range 32768 through 65535 may be sent in two different forms: either as themselves
or as negative numbers in the range -32768 through -1, respectively; i.e., as the desired value
minus 65536. For example, the following two commands are equivalent:
XD 3, 65532;
XD 3, -4;
Where a numeric parameter is expected, the value of an ACL variable can be substituted.
For more information about variables, please see Chapter 10.
Getting Status Information
Several ACL commands and escape sequences cause the Automove System to send one or
more numbers back to the host. When this occurs, the numbers are always separated by
commas; after the last one, the System sends the Output Terminator sequence. At power up
this sequence defaults to Carriage Return and Linefeed. It can be changed via the
ESC.M
command; see Chapter 6.
When the System sends fractional numbers it suppresses trailing zeros after the decimal
point, and suppresses the decimal point itself if the fractional part is zero. See, for example,
the OC command.
When the System sends whole numbers back to the host, it always uses the "normal"
representation: 0 through 65535. No decimal point is sent. See, for example, the OZ
command.
See Outputs to the Host in Chapter 5.
