SHORT SUMMARY of PURPOSE:                                                
                                                                                
 Fill an array with true track information. (Then calls FFXTRP to               
 do it again if the fast tracking banks are available - not the                 
 most efficient way to do it!)                                                  
                                                                                
LIST and DESCRIPTION of INPUT VARIABLES/ARGUMENTS:                       
                                                                                
 JTRUE - the true track (STR) number                                            
                                                                                
 FS/STR/SVX banks (true track/vertex information)                               
                                                                                
 Geometry information in /FKCONS/                                               
                                                                                
LIST and DESCRIPTION of OUTPUT VARIABLES/ARGUMENTS:                      
                                                                                
 Fills the TRUE array (in /FKTRUE/) with the true track parameters              
 at each plane
