The second parameter of %EDITC is not a character constant of length 1.
20
Cause . . . . . : The second parameter of %EDITC, representing the edit code, must be a character constant of length 1. It can be a literal, a named constant or a character expression whose value is known at compile time. The built-in function is ignored.
Recovery . . . : Correct the value of the second parameter so that it is a valid edit code. Compile again.
