To get more information about a specific trap use the HELP command with the parameter 1930+trap number.
Examples:
REM *** Help for Trap 2 (1930+2 = 1932) HELP 1932 REM *** Help for Trap 0E (1930+14 = 1944) HELP 1944
To find the program that caused a trap you can use the program exeinfo.exe (available on hobbes for example (see Internet - Web Pages)).
Search the line beginning with CS:EIP in the trap output and write down the number after CSLIM. After rebboting the PC you can use the command
exeinfo -f -l####
(where #### are the last 4 digits of the number after CSLIM=) to get the program that caused the error.
Example: If the trap output contains the line
CS:EIP=0658:00001a5c CSACC=009b CSLIM=00004e3a
the exeinfo command is
exeinfo -f -l4e3a
