Hi all, 1. Error in loop mechanism? The absolute, and the x,y,z errors are always the same? I don't believe that this is true. Seem to be a bug (probably from the installed survex?). cavern (survex) 1.0.38 is currently installed ######################### loop errors ########################## REL-ERR ABS-ERR TOTAL-L STS X-ERROR Y-ERROR Z-ERROR STATIONS 0.88% 1.0m 1.0m 10 1.0m 1.0m 1.0m [2@michael.Tham-omar-kok - 4 - 44 - 43 - 42 - 41 - 7 - 6 - 5 - 3 - 2] ##################### end of loop errors ####################### 2. In case of a typo between the station list (forgotten tab or blank) no line info is giffen, where the error occurs. It would always be nice for debugging in which line the error occurs. 3. Is it possible to use blanks in survey names (like survey "Tham Nam Eng")? Many thanks Wolfgang
