DSXchange

Num() function will report whether the data is numeric. You can also use the Matches operator - for example Matches 1N0N.
Finally you can use oconv(string,"MC/N") and see if there's anything remaining.

Get the pathname right. NUL file is in the folder; therefore the pathname is either NUL alone or .\NUL (the dot means "current folder") - not \NUL which means "the nul file in the root directory of the drive.
And, of course one L not two for Windows.

The NUL file (or /dev/null if you're on UNIX) can deliver an infinite number of "presses of Enter". Try something like the following if default answers are OK. Call DSExecute('DOS', '7z x ' : Filedir : '\' : ZipFile : " < .\NUL", Output, ReturnCode) Ans = Output

Might it be that not all arguments are being passed to the routine?

I always include traps for UnAssigned() and IsNull() for routine arguments in the routine code.

Welcome aboard. This question is too vague. The structure of the Repository is intentionally sparsely documented by the vendor. The DataStage Repository has not been UniVerse since version 5.2; if you want to know more about UniVerse then I suggest you visit IBM's website for UniVerse and UniData

The statement is true in version 7.5 and later.

So it's a parallel job. Continued in that forum.

at is used for "one shot" schedules, cron for repeating schedules. It was thus in earlier versions also.
Note that this is the UNIX command at and not the Windows command AT.

Tell us more about these commands. Where did you find them? Were they perhaps provided by IBM France?
These commands are not, as far as I know, part of the standard DataStage suite.

What error message is being generated?

Save the table definition from your Sequential File stage, then view it as a schema file (on the Layout tab) to learn how it's done.

APT_STRING_PADCHAR is not relevant to VarChar data types. Why do you claim that "OCI stage assuming null for field containing only one space"? What is populated into the table (use a query with NVL function) or, if there is an error message, please post that. In short, debug! Send (a relevant sample...

If it's in VOCLIB, then

It it's not in VOCLIB but is in another job log, then

Note that neither of these is SQL, so there is no terminating semi-colon.
