Hello all,
I would like to get the answer for why -1 is moved to the length field in dynamic symbolic cursor positioning technique,why not any other thing?
Please reply.
the name+l field is normally used for specifying the length of its contents or infact the lenght of data being entered to the field....
infact we check the name+l field to see if any value has been enterd into the specified field or not to give out an error condition during appl development..
when a clear command is executed the length field contents are made to 0 where in by default the initial value was -1[without any value].
so inorder to sent the field back to its initial posiotion with cursor control in it..it is given the -1 value.
