How do I find out the TOS language version installed?

[wyerd]

Is there a way to interrogate what language TOS is in C? For example, if it’s US English, the date will be displayed as MM/DD/YY, if any european language it’ll be displayed DD/MM/YY.

If available, use the _IDT cookie to determine the user's/OS's preference how to display a date: http://toshyp.atari.org/en/003007.html#Cookie_2C_20_IDT
Otherwise, the sysbase variable points to an OSHEADER structure, whose os_conf member will tell you the TOS language.

Great, thanks. I’ll look into these.

There is cookie less way - in TOS header there is region/language flag. Word at offset $1C . 7 is UK English, 3 is German .... You can find more details after little search.

Yes, as I already wrote above: "Otherwise, the sysbase variable points to an OSHEADER structure, whose os_conf member will tell you the TOS language." However, the cookie -- if present -- should take preference when displaying a date/time to the user.

Thanks for the info. I found a PDF for the Atari Compendium- it’s one helluva reference guide!
