Debug options

Debug command line options (D, E)

D and E ( !DEBUG, !DEBUG 2) invoke debug mode and increase the information written to the screen or .asl file. This information is not useful to most users. On Unix systems, if ASReml is crashing use the system script command to capture the screen output rather than using the L option, as the .asl file is not properly closed after a crash.

Logfile (L)

L ( !LOGFILE) requests ASReml write screen output to a file with filename extension .asr. Debug output is directed to this file.

Timing information

One of the pieces of information reported by !DEBUG is the execution time required for various parts of the first iteration. The other information is not helpful to the general user.
