# 0050: Not enough parameters for command

The compiler can't get a required number of parameters for the [command](/language/instructions/built-in-commands.md), [directive](/language/directives.md) or [class](/language/instructions/classes.md) member.

It may happen if fewer parameters are provided or some of them are invalid. The number of parameters for each built-in command is hardcoded and can't be changed. The number of parameters in the class corresponds to the underlying [opcode configuration](/edit-modes/opcodes-list-scm.ini.md).

**Possible solutions:** provide the required number of parameters:

```
{$INCLUDE} // error, one parameter missing
Player.Defined() // error, one parameter missing
INC() // error, expected two parameters

{$INCLUDE file.txt} // OK
Player.Defined($PLAYER_CHAR) // OK
INC($var) // OK
```
