NOTMNAME, XXXX is not a valid M name
Compile Time Error: M names must be ASCII, start with a "%" or an alpha and thereafter contain only alphanumeric characters. In GT.M M, names are currently functionally limited to 31 characters, in most cases, by truncation.
Action: Correct the, typically routine, name to comply with the supported format. Names are also used for labels and both global and local variables. Note that GT.M usually truncates names longer than its supported maximum, which, FIS recommends against as, while it can provide embedded information, can lead to ambiguity or other unintended behavior.
