The M2 compiler you cannot remember is probably the Lilith Modula-2 compiler. In this case the implementation restriction applies for VAR-parameters only. Lilith is word-addressed and thus not able to pass the address of an element of a character array. Andreas Borchert -- borchert@mathematik.uni-ulm.de borchert@dulruu51.bitnet
