Arguments

bits

A bit-coded integer that allows or disallows certain types of user input.
The bits can be added together in any combination to form a value between 0 and 255.
If no bits argument is supplied, zero (no conditions) is assumed.
The bit values are as follows:

1 (bit 0)  Prevents the user from responding to the request by entering only ENTER.

2 (bit 1)  Prevents the user from responding to the request by entering zero.

4 (bit 2)  Prevents the user from responding to the request by entering a negative value.

8 (bit 3)  Allows the user to enter a point outside the current drawing limits.
This condition applies to the next user-input function even if
the AutoCAD system variable LIMCHECK is currently set.

16 (bit 4)  (Not currently used.)

32 (bit 5)  Uses dashed lines when drawing a rubber-band line or box.
For those functions with which the user can specify a point by
selecting a location in the drawing area, this bit value causes
the rubber-band line or box to be dashed instead of solid.
(Some display drivers use a distinctive color instead of dashed lines.)
If the system variable POPUPS is 0, AutoCAD ignores this bit.

64 (bit 6)  Prohibits input of a Z coordinate to the getdist function;
lets an application ensure that this function returns a 2D distance.

128 (bit 7)  Allows arbitrary input as if it is a keyword,
first honoring any other control bits and listed keywords.
This bit takes precedence over bit 0;
if bits 7 and 0 are set and the user presses ENTER, a null string is returned.

Note  Future versions of AutoLISP may use additional initget control bits,
so avoid setting bits that are not listed here.

string

A string representing a series of keywords.
See Keyword Specifications for information on defining keywords.
