Hi Lee, If booting from a Win drive on the first instance of needing to load the Turbo toolkit check for the existence of a file on the boot device called "TTKLoaded", or similar. If the file does not exist create it and load TurboTK. If the file is found to exist do not load the toolkit. At the end of the session tidy up the boot device by deleting this file. Not elegant but practical.

MANIFEST is pretty ideal for this.>>>> Tobias>>>> Am 17.08.2017 um 11:25 schrieb Tobias Fröschle via Ql-Users <>>> email@example.com>:>>>>>> Lee,>>>>>> there are a number of toolkits that allow you to check for specific>>> other toolkit commands loaded or not - But this is a bit useless as it>>> leaves you with a chicken-and-egg problem: How to check whether the>>> checking toolkit is loaded?>>>>>> Your best bet on SMSQ/E would be a WHEN ERRor clause you place just in>>> front of a Toolkit command you are about to execute:>>>>>> 1000 TurboTkLoaded = 1>>> 1010 WHEN ERRor>>> 1020 TurboTkLoaded = 0>>> 1030 END WHEN>>> 1040 REMark Execute a Toolkit command>>> 1050 MANIFEST : x = 100>>> 1055 REMark de-activate error checker>>> 1060 WHEN ERRor>>> 1070 END WHEN>>> 1080 PRINT "Turbo Toolkit loaded:"!TurboTkLoaded>>>>>> On a QL with non-working WHEN ERRor commands (pre-MG) you are a bit>>> doomed, the only thing I could probably come up with is writing a BASIC>>> program that PEEKs the name list, which is not quite so simple.>>>>>> Tobias>>>>>>>>> Am 17.08.2017 um 10:49 schrieb Lee Privett via Ql-Users <>>>> firstname.lastname@example.org>:>>>>>>>> I originally posted this on the forum:>>>>>>>> Hi community, I have searched for this on the forum but cannot find an>>>> entry but I am sure this has been asked before.>>>>>>>> I currently test for the presence of the HBA ROM in a boot program using>>>> VER$ and would like to test for other toolkits, specifically the TURBO>>>> toolkit.
