Hi,
many OPL users asked me about range arrays.
They want to write something like
{string} centuries={“XIX”,”XX”};
range years[centuries]=[1800..1899,1900..1999];
execute
{
writeln(years);
}
But with CPLEX 12.9 that’s not allowed and you get an error.
Instead you could write
{string} centuries={“XIX”,”XX”};
int yearsLB[centuries]=[1800,1900];
int yearsUB[centuries]=[1899,1999];execute
{
for(var i in centuries) writeln(i, ” : from “,yearsLB[i], ” to “,yearsUB[i]);
}
which gives
XIX : from 1800 to 1899
XX : from 1900 to 1999
