MSIR.0561 ($Function): (error) in line (lnum), procedure (pname), file (fname)
The indicated $function in line lnum of procedure pname in file fname was invoked incorrectly.
error indicates the exact nature of the error; for some $functions, if the error is specific to one of its arguments, it may begin with a string of the following form:
(argument n)
This indicates that the error is due to the nth argument.
The request is cancelled. Correct the $function invocation.
