The invention pertains to a method for identifying compounds that inhibit the erythropoietin-induced JAK2 kinase activity in vivo. Preferably, two points on control line whose distance from a closer end of a range in which skew is to be suppressed is equal to \xbc of the total length of the range may be selected as the dividing points at which the control line is driven. A second message is associated to the memory error when the memory error has occurred, the second message explaining the memory error. Related methodology is also disclosed.
