I looked at a dump of HIP8.DAT and came up with this possible QBASIC/QUICKBASIC 4.0 code which appears to do it ( for I! >1 ) Of course you will have to change the hardcoded SkyMap path. TYPE HIP8 RA AS DOUBLE Dec AS DOUBLE Mag AS SINGLE RAprec AS SINGLE DecPrec AS SINGLE END TYPE DIM Star AS HIP8 Form$ = "###.########## ###.########## ##.######## ##.######## ###.##" F$ = "C:\386\D-DISK\SATPROG\SKYMAP\hip8.dat" OPEN F$ FOR RANDOM ACCESS READ AS #1 LEN = 28 FOR i! = 44455 TO 44465 GET #1, i!, Star PRINT USING Form$; Star.RA; Star.Dec; Star.RAprec; Star.DecPrec; Star.Mag NEXT i!
