Return Codes from EXECIO

After an EXECIO command runs, it sets the REXX special variable "RC" to a return code. Valid return codes from EXECIO are:

Return Code	Meaning
0	Normal completion of requested operation.
1	Data was truncated during DISKW operation.
2	End-of-file reached before the specified number of lines were read during a DISKR or DISKRU operation. (This return code does not occur when * is specified for number of lines because the remainder of the file is always read.)
4	An empty data set was found within a concatenation of data sets during a DISKR or DISKRU operation. The file was not successfully opened and no data was returned.
20	Severe error. EXECIO completed unsuccessfully and a message is issued.
