objectTypes

 objectTyp and objectID
  objTyp (int) or (char)  Typ_PT   'P'         _typ_
    "P12"       P is the objectType (Typ_PT)

AP_typ_srcExpr decode expression
AP_typ_FncNam get type of function
AP_src_typ__ get objTypTxt from typ
DB_Typ_Char give typ(int) from text "PT" --> Typ_PT;
AP_cmp_typ check for identical types
UTO_ck_oTyp check object-typ (struct or object)
UTO_ck_typTyp check if typ=curve (Typ_lFig) or surface (Typ_SUR)
UTO_ck_curvLimTyp check if CurveLimits are Points or parameters
UTO_ck_curvForm check if objTyp is ObjGX or other typ
UTO_ck_surfTyp returns surfSubTyp
AP_ck_ftyp returns fileTyp as int; 0=native, 1-9=Import, 10-19=Mockup
AP_i2ftyp returns fileTyp as text

objectIDs

 objectTyp and objectID
  objID  (char*)                   "P123"      _oid_
    "P12"       P is the objectType (Typ_PT)
APED_oid_dbo__ make name from typ and DB-Index (visible object types)
APED_oid_dbo_all make name from typ and DB-index (all types)
SRC_src_dbo create sourceCode of requested type from Database-object
APED_oid_vc get oid for Vector; (DX or DIX or D#)
AP_obj_add_obj add objname to string
AP_obj_add_pt add Point* as "P(xyz)"
AP_obj_add_vc add struct Vector* to string " D(x y z)"
AP_obj_add_val add double > text ( xa_obj_txt.c )
AP_cre_defHdr create new (unused) objHeader
AP_src_typ__ get typText from typ (eg "PT" for Typ_PT)
AP_src_typMod get modifier-text from (modifier)typ
APT_decode_print create sourceObj from atomicObjs (for PRInt-cmd)

objectName

is      eg "#height 2 floor"
APED_lNr_objNam get sourcelineNr from ObjName
APED_onam_search search objName between ps and pe

DB-Objects

DB-Obj: _dbo_ objectType and dataBaseIndex
