Error Code Constants

Error Code Constants​

Every error and warning number has a name, such as ERROR_DIVZERO (50) or WARNING_VARNOTASSIGNED (65549). Most of these names are also constants in BASIC-256, so a program can compare LastError with a name instead of a number. Like all constants they may be written in small letters.

The full list of numbers, names and messages is on the Error Codes page. The names marked † there have only a number, not a constant.

Example​

try
   print 1 / 0
catch
   if lasterror = error_divzero then print "division by zero"
end try
print error_divzero
print warning_varnotassigned

will display

division by zero
50
65549
