;; PlaceText.lsp Version 1.0 Beta
;; Allow user to place text with enhanced features
;;
;; Copyright© 2009 Charles Alan Butler aka CAB from TheSwamp.org
;;
;; USAGE -> (PlaceText <vlaObject> '(Option Flags))
;; Move point is based on the Alignment point of the text
;;
;; Options Flags -> List of pair list
;; Option pairs may be in any order & may be omitted for default values
;; (list '(<String> <Data>) '(<String> <Data>))
;; <String> = string for option identification
;; Identifier DataType Default Action
;; "erase" Logic true erase text if user exits using ENTER
;; "curve" Logic true Allow Curve Align Option
;; "textgap" Real 0.1 step amount for text gap
;; "rotationstep" Real 0.0174533 step amount for rotation
;;
;; (PlaceText <vlaObject> '(("erase" nil))) = use default options
;;
;; RETURN -> an error message or nil if successful
;;
;; -=< User Options >=-
;; >> Enter = Exit
;; >> Space = Rotate CCW
;; >> Shift + Space = Rotate CW
;; >> Tab = Rotate 90 deg
;; >> Shift + Tab = Mirror Rotation
;; >> C = Curve Aligned, place text next to curve object
;; >>> [A] = toggle auto angle correction
;; >>> [P] = Text Perpendicular to object, also [Tab]
;; >>> [+] = Adjust Offset from object
;; >>> [-] = Adjust Offset from object
;;
;; Thanks to Lee Mac for ideas & code from his NumInc.lsp

;; Need to add Trap for ESCape key <---------------<<<<
;; May include a Layer Override feature in future
