So that you don’t have to catch hundreds of individual exceptions, the exception classes related to Synergy/DE runtime errors are organized in a hierarchy that groups common exceptions and like items together. You can use the classes in the hierarchy like this:
proc
try
open(1, i, 'LOC:myfile.tst')
catch (e, @Synergex.SynergyDE.NoFileFoundException)
writes(15, "File not found")
catch (e, @Synergex.Synergyde.FileIoException)
writes(15, "Other file open error - Error "+%string(e.errno))
catch (e)
writes(15, "Other system exception")
endtry
When catching the exception, you can determine the underlying Synergy/DE error number with the Errno field of the exception variable. For example,
catch (e, Synergex.SynergyDE.BadDigitException)
writes(15, %string(e.Errno))
Synergy exception class hierarchy
The following exception class hierarchy is supported. Each indented class is derived from its parent (the lesser indented or bolded) class. See Synergy exception class error mapping for a list of errors that map to each exception class.
All exception classes are derived from System.Exception.
