Introduced in the 1995 ANSI M[UMPS] language standard.
This variable provides information about the error-conditions that are unresolved.
IF $ECODE[",M6," WRITE "Undefined local variable"
Note: the leftmost character of the value of $ECODE is always a comma. This means that every error code that is stored in $ECODE is surrounded by commas. If $ECODE contains "M61", it would also contain "M6", so it is better to include the commas in the value to check for: check whether $ECODE contains ",M6,".
For more examples of the use of special variable $ECODE, see the function $STACK.
