RE: Open with USROPN Files

["Bill Hopkins" <BHopkins@xxxxxxxxxxxxxxxxxxx>]

Jon,

Did you see my post with file name coming in as field from file. Can I 
loop like I showed? Using the one F Spec. for all files and then use 
actual file nameS  on reads chains etc.

Maybe I did not explain myself clearly but as far as QCMDEXC string build 
with variable from file  I said I knew that. 
Just trying  to do the same with OPEN. 

After reading manual and posts it looks to me that it can be a variable 
from a file  using EXTFILE but it is a one to one. Meaning once I move in 
variable in to File and 
OPEN File that's it and I can't keep repeating with same F Spec and 
different variables. 

Is that truth.

Thanks 
Bill Hopkins

 >> Is it truth that there is no way to do this:

As has been pointed out earlier you can do what you want with QCMDEXC or
system, but since you asked the question......

The answer is "Yes" for V5R1 and later.  V5R1 introduced the F-spec 
keyword
EXTFILE.  This allows for a literal file name to be used or for a variable
to be used to supply the file name.  There is also a matching EXTMBR
keyword.  As long as the variable is set _before_ opening the file this
works just fine.  The example below demonstrates passing the file name in 
as
a parm and also using USROPN.

     FFile2     IF   F   10        DISK    EXTFILE(FileName2)

     FPrinter   IF   F   10        DISK    EXTFILE(PrtName) USROPN

     D PrtName         S             21A
     D FileName2       S             21A
     D Testing         S               N

     C     *ENTRY        PLIST
     C                   PARM                    FileName2
     C                   PARM                    Testing

      * Use test library print file when testing
     C                   IF        Not Testing
     C                   EVAL      PrtName = 'PRODLIB/PRTFILE'
     C                   ELSE
     C                   EVAL      PrtName = 'TESTLIB/PRTFILE'
     C                   ENDIF

     C                   OPEN      Printer
