0Initial value:
Displays the number of the appropriate error code when an AutoLISP function
call causes an error that AutoCAD detects.
AutoLISP applications can inspect the current value of ERRNO with (getvar
"errno").
The ERRNO system variable is not always cleared to zero. Unless it is inspected
immediately after an AutoLISP function has reported an error, the error that
its value indicates may be misleading. This variable is always cleared when
starting or opening a drawing.
See the AutoLISP Developer's Guide for more information.
