Origin: 2020b
Operating System: W10Pro 1809
Exist() does not work with string arrays.
I would appreciate any helpful hint. |

Got it, thank you.
Where does one read more about {...} wrap?

Akazak,
To expound on what Nick said,
sa;
causes an error if the StringArray doesn't exist, so
stringarray_exists = 1;
would never get called and the script would abort.
But, wrapping the error-causing code in {} allows the error to get swallowed and the script jumps to after the closing }. The script continues without
stringarray_exists = 1;
ever getting called.
I hope this helps.
Thanks,
Chris Drozdowski

Hi,
It's kind of error handling.
https://www.originlab.com/doc/LabTalk/guide/Error-Handling
stringarray_exists is a variable (not function) which stays 0 in case if {...} fails.
Best,

Still didn't get the trick by Chris.
Appreciate any details.

Hi, Chris,
Thank you for the coding trick - it is really amusing. However it does not work in the particular case - I do not understand, why. Unfortunately I cannot check it with different Origin versions anymore.
Anyway, many thanks and
Regards,

Hi, James,
thank you for your response!
Is it possible to make this type deletable as well?

if(sa.GetSize()==0/0)
type "no sa";

Hm.
Is stringarray_exists a function returning int?
Why non-existing sa; will prevent stringarray_exists = 1; ?

Hi,
Exist() function doesn't search StringArray according to:
https://www.originlab.com/doc/LabTalk/ref/Exist-func
I will report it to see if we are going to improve it.
