☜	Error Code M20 M[UMPS] by Example					☞

M20, line must have formallist

Introduced in the 1995 ANSI M[UMPS] language standard.

When an extrinsic function is invoked (e.g. $$XXX^YYY(P1,P2)), and the label in the routine that is invoked to calculate the function value does not have a parameter list (in this example, the label XXX in routine YYY), this error will occur.
