* Fonctions preparatoires:
* Gn =
* G01 interpolation lineaire ( trace de droites )
* G02,G20,G21 Interpolation circulaire , sens trigo < 0
* G03,G30,G31 Interpolation circulaire , sens trigo > 0
* G04 commentaire
* G06 Interpolation parabolique
* G07 Interpolation cubique
* G10 interpolation lineaire ( echelle 10x )
* G11 interpolation lineaire ( echelle 0.1x )
* G12 interpolation lineaire ( echelle 0.01x )
* G52 plot symbole reference par Dnn code
* G53 plot symbole reference par Dnn ; symbole tourne de -90 degres
* G54 Selection d'outil
* G55 Mode exposition photo
* G56 plot symbole reference par Dnn A code
* G57 affiche le symbole reference sur la console
* G58 plot et affiche le symbole reference sur la console
* G60 interpolation lineaire ( echelle 100x )
* G70 Unites = Inches
* G71 Unites = Millimetres
* G74 supprime interpolation circulaire sur 360 degre, revient a G01
* G75 Active interpolation circulaire sur 360 degre
* G90 Mode Coordonnees absolues
* G91 Mode Coordonnees Relatives
*
* Coordonnees X,Y
* X,Y sont suivies de + ou - et de m+n chiffres (non separes)
* m = partie entiere
* n = partie apres la virgule
* formats classiques : m = 2, n = 3 (format 2.3)
* m = 3, n = 4 (format 3.4)
* ex:
* G__ X00345Y-06123 D__*
*
* Outils et D_CODES
* numero d'outil ( identification des formes )
* 1 a 99 (classique)
* 1 a 999
* D_CODES:
*
* D01 ... D9 = codes d'action:
* D01 = activation de lumiere (baisser de plume) lors du d<>placement
* D02 = extinction de lumiere (lever de plume) lors du d<>placement
* D03 = Flash
* D09 = VAPE Flash
* D51 = precede par G54 -> Select VAPE
*
* D10 ... D255 = Indentification d'outils ( d'ouvertures )
* Ne sont pas tj dans l'ordre ( voir tableau dans PCBPLOT.H)
