I am looking at analysing a sting using an FB in SCL.
I have looked at these

https://support.industry.siemens.co...-different-data-type-in-s7-scl?dti=0&lc=en-WW
http://plc4good.org.ua/files/03_downloads/SCL_table/SCL-cheat-sheet.pdf
but I am falling at the first hurdle. When I try and input things like VAR and LEN TIA portal is coming up that "Tag VAR not defined". According to what the guides I am using VAR is an instruction.
I cannot see what i'm doing wrong?!
I have an S7-314.
Thanks
