M/Error List

M Error List

This is the list of errors from the MUMPS Standard. Download PDF: File:Mumps 1995 err book.pdf

Any implementation of STANDARD MUMPS should have the M-Error as part of the value of the special intrinsic variable $ECODE .

M-Error	Official Explanation	English Explanation
M1	naked indicator undefined	Introduced in the 1995 ANSI M[UMPS] language standard. The naked indicator is undefined at the start of a M[UMPS] process, or after a reference to an unsubscripted global variable has been made. The sequence of commands SET ^A=3,^(4)=5 would cause this error to occur.
M2	invalid combination with P fncodeatom	$FNUMBER format combination problem
M3	$RANDOM seed less than 1
M4	no true condition in $SELECT
M5	lineref less than zero	offset for $TEXT is bad
M6	undefined lvn	some local variable is undefined
M7	undefined gvn	some global variable is undefined
M8	undefined svn	bad name for special intrinsic variable
M9	divide by zero	possibly bad math. Some code: Assertion failed
M10	invalid pattern match range
M11	no parameters passed
M12	invalid lineref (negative offset)
M13	invalid lineref (line not found)
M14	line level not 1
M15	undefined index variable
M16	argumented QUIT not allowed
M17	argumented QUIT required
M18	fixed length READ not greater than zero
M19	cannot copy a tree or subtree into itself
M20	line must have formallist
M21	algorithm specification invalid
M22	SET or KILL to ^$GLOBAL when data in global
M23	SET or KILL to ^$JOB for non-existent job number
M24	change to collation algorithm while subscripted local variables defined
M26	non-existent environment
M27	attempt to rollback a transaction that is not restartable
M28	mathematical function, parameter out of range
M29	SET or KILL on ssvn not allowed by implementation
M30	reference to glvn with different collating sequence within a collating algorithm
M31	controlmnemonic used for device without a mnemonicspace selected
M32	controlmnemonic used in user-defined mnemonicspace which has no associated line
M33	SET or KILL to ^$ROUTINE when routine exists
M35	device does not support mnemonicspace
M36	incompatible mnemonicspaces
M37	READ from device identified by the empty string
M38	invalid ssvn subscript
M39	invalid $NAME argument
M40	call-by-reference in JOB actual
M41	invalid LOCK argument within a TRANSACTION
M42	invalid QUIT within a TRANSACTION
M43	invalid range value ($X,$Y)
M44	invalid COMMAND outside of a transaction
M45	invalid GOTO reference
M57	more than one defining occurence of LABEL in ROUTINE
M58	too few formal parameters
