No operators are allowed in the data section. Thus,
set K:= 0..Deadline ;
means specifying a plain set K that consists of the only element, which
is a string literal "0..Deadline". However, the error occurs because K
is declared as a set (array) of sets rather a plain set.
Please look at examples in the language reference and those included in
the glpk distribution.
