Metal In General: System Errors                                     Page 


Metal System Errors



The following is a list of Metal System Errors (SYSERR). For each one, there is the error text that Metal displays, and the value of SYSERR in both hex (base 16) and decimal (base 10, what us humans use). By using this table, you can setup a series of TRAPs for certain SYSERR values - for example:

       TRAP SYSERR=160 goto IntegerOverFlow
       TRAP SYSERR=211 goto MissingLabel

Note that the Missing Data error will display the command word or character that it was expecting to be next - usually, this is the "(" character, but the second most common one is the comma (","), followed by TO and MODE.


                                      SYSERR values:
