MSIR.0506 Invalid value (val) for SIRFACT (cmd) ($func) command
A cancellation value, 'val', that could not be converted into a valid floating point number was specified for a $function that returns a numeric value for a SIRFACT CANCEL command. Since 'val' is not a valid floating point value, it cannot possibly be returned by '$func' so does not make sense as a cancellation value. Re-issue the SIRFACT CANCEL command either correcting the value or not specifying it.
