Pascal III: Mapping of SOS error codes

Pascal III: Mapping of SOS error codes

Pascal III maps SOS error messages 1 to 5 as Pascal error numbers 123 to 127
because of a numbering conflict.
 
For example, a user of Great Plains software, a Pascal III-based software
package, posted Accounts Receivable and encountered a system crash during the
merge or printing of the sorted sales journal. The system reported SOS error
123, so the error was really SOS error 01, Invalid SOS call number.
