Officelite "Type Expected" Error

Officelite: KSS 8.6.2

WorkVisual: 6.0.26

This one should be pretty quick, but I can't wrap my head around it.
This is the code:

GLOBAL STRUC T_CARR_POS_PAR E6POS APPR, READ, PREL, DEP, MOVE, E6AXIS XAPPR, XREAD, XPREL, XDEP, XMOVE, FRAME SCAN, OPEN, MIDDLE, CLOSE, PREL_OFFSET, DEP_OFFSET, CurrentPlane, InfPlane, SupPlane, BasePlane

It's a single structure composed by E6POS elements, the relative E6AXIS elements and finally some FRAME elements.
If I write this in a .dat file on WorkVisual no error is given. However, when the project is uploaded on Officelite, I receive this:
Error no. 2327 Type Expected.

I also defined a different structure with only E6POS variables and it works fine. The above-defined structure is, with many other, part of a bigger structure, but this is the only one which causes error.

Thanks for any help!

Hi hermann,
Thanks a lot for the suggestion, will take a look into it in a second and try to eliminate each word until I find the one (at work I tried to take a look at the column-pointed word, but didn't seem to be the right one...)
Will also search a list of this reserved keyword, in the document I looked there's only a small list used as an example of the most important ones.
Thanks again!

Quote from panic mode

you probably have issue with READ, MOVE, OPEN, CLOSE

change their names and see if it works

Hi panic mode , thanks a lot for the help.
Was just trying cancelling those words one by one. Apparently MOVE, OPEN and CLOSE are the reserved keywords you need to avoid using in structure, while READ doesn't give me any error.
