Re: finding whether file exists or already opened

Check %status.
See page 77 of the ILE RPG reference, which is page 97 of the manual at:
http://publib.boulder.ibm.com/html/as400/v5r1/ic2924/books/c0925083.pdf
Code    Device 1 RC 2 Condition
01215   all      n/a  OPEN issued to a file already opened.
01216 3 all      yes  Error on an implicit OPEN/CLOSE operation.
01217 3 all      yes  Error on an explicit OPEN/CLOSE operation.
3. Any errors that occur during an open or close operation will result in a
*STATUS value of 1216 or 1217
regardless of the major/minor return code value.

(I don't think major/minors apply to disk files.)

Maybe the File Information Data Structure may help:
Table 5. Contents of the File Feedback Information Available in the File
Information Data Structure
(INFDS) (continued)
From   To

number.

See page 66 of the same manual, which is pdf page 86.

I need to know if a file does not exist or is already open when using the
'open' opcode.  But there are not separate indicators for 'does not exist'
and 'already open'.  Can %error be used?  If so, how?
