MSIR.0750 Class (cl) method (meth): (error) in line (lnum), procedure (pname), file (fname)

Method meth of class cl was invoked incorrectly at line number lnum of procedure pname in file fname.

error indicates the exact nature of the error. For some methods, if the error is specific to one of its arguments or to the object method, it may begin with a string of one of the following two forms:

1. (argument n)

   This indicates that the error is due to the nth argument.

2. (method object)

   This indicates that the error is due to the object to which the method is applied.

The request is canceled. Correct the method invocation.
