Error message Description
not enough memory
Memory shortage has occurred.
Review the program.
attempt to call global 'readformatEvent' (a nil value)
The readformatEvent function does not
exist.
Write the readformatEvent function.
attempt to call global 'nameformatEvent' (a nil
value)
The nameformatEvent function does not
exist.
Write the nameformatEvent function.
FmtSet.lua:○: cancel
Aborted while the program is running.
• Aborted by the CANCEL command
• Aborted due to the timeout of the
program execution time
Check if the program is not
supposed to go into the infinite loop
or the process time of the program is
too long.
