Has anyone else had problems with the Concat function on the Sparc series of SUN workstations (SUNOS4.1)? Modula-2 Version 2.2.2 Try this code: ---------------------- MODULE t; FROM String IMPORT Assign,Concat; FROM SimpleIO IMPORT WriteString,WriteLn; VAR result:ARRAY [0..255] OF CHAR; rcode:BOOLEAN; BEGIN Assign("bbb",result,rcode); WriteString(result); WriteLn; Concat("aaa",result,result,rcode); IF NOT rcode THEN WriteString("Failed"); WriteLn; END; WriteString(result); WriteLn; END t. ---------------------- The Concat function returns false and fails, corrupting the result string, on a sparc. The same code succeeds on a SUN 3/60. Does anyone have an in with SUN to know if a patch is available. -- Allen Delaney (allen@brc.ubc.ca) Biomedical Research Centre, U.B.C., Vancouver, B.C.
