Automic Workload Automation

Is there a way to determine if a variable is defined or declared on run time before it is actually executed ?
I tried using GET_DATATYPE(variable) to see if variable is declared or not based on the data type that was returned,  but its just returning blank response.

Please suggest..

I don't know of a function to find out if a variable is defined in Automic script.

There is a rather silly trick though: You can initialize any variable by itself, like so:

:set &dirty_hack# = &dirty_hack#

If &dirty_hack# had a value before, that value will be retained. If &dirty_hack# was not initialized, it will now be initialized and empty, so you can distinguish with:

:if &dirty_hack# = ""
:  print "empty"
:else
:  print &dirty_hack#
:endif

And more importantly, your script will now not fail with an U00021719: Undefined Variable error. At the expense of making your script a little bit larger, wasting a few bytes and CPU cycles, and being a bit silly.

Kudos once more to MatthiasSchelp for pointing me to this.

Hi

unfortunately not out of the box...

in short you can use e.g. tis code snippet:

:SET &SCRIPTVARA# = "&SCRIPTVARA#"
:IF &SCRIPTVARA# = "" OR " "
!   FURTHER CODE to avoid an unset (=empty) Scriptvara
:ENDIF

here was a discussion about that with lots of informaton.

Thanks Carsten Schmitz & Wolfgang Brueckler.
Can you tell me how this function : GET_DATATYPE(variable) works. I tried calling this function but its just a blank response.

I don't know of :GET_DATATYPE, I can not find it in the Automic documents or in Google. Can you let us know where you found it? Thanks!

I know of :GET_OBJECT_TYPE, but it is no use for script variables. It only works for persistent objects, such as Jobs or probably VARA objects.

@ Carsten Schmitz : You can check directly in automic by typing GET_ and Ctrl + Space to see list. However, even i do not see in documentation. Also, I see that it accepts variable as a parameter. So, I just assume it should return the data type (Signed, Unsigned, String and float) as a result.

Thanks, that's interresting. But I now remember a similar thing: Automic ships a file that is seemingly used for syntax checking in the script editor. I think it's called syntax.bin or something like that. I looked through it a long while ago, and found functions that were in it, but not fully implemented in the engine.

GET_DATATYPE may be one of those, a placeholder for future implementation, or an abandoned feature.

Best regards and have a good weekend,
Carsten

Thanks Carsten Schmitz  :)
