A variable is used in a expression, but was neither passed as argument nor set before.
Declare or define as argument the variable you need to use, or remove the reference to the undefined variable.
Non-compliant code
Following code will compile, but on runtime the Add method will fail with "UNDEFINED error" message.
Method Add()
{
Set a=1
Set c=a+b // b is UNDEFINED
Write !,c
}
Compliant code
Method Add(b AS %Numeric)
{
Set a=1
Set c=a+b
Write !,c
}
