Unsuccessful Execution
When a verb does not execute successfully, SNAplus2 returns a primary

provide specific details about the reason for unsuccessful execution.
Parameter Check If the verb does not execute because of a parameter
error, SNAplus2 returns the following parameters:
primary_rc SV_PARAMETER_CHECK
secondary_rc Possible values are:
SV_INVALID_SET
The dt_set parameter contained a
value that was not valid.
SV_INVALID_RESET_TRACE
The reset_trc parameter contained
a value that was not valid.
Other Conditions Other conditions canresult in the following primary
return codes ( primary_rc ):
SV_INVALID_VERB
The opcode parameter did not match the operation
