I'm working on implementation of a simple SCPI parser for an instrument that will support VISA API. I wonder if there are any restrictions to support commands that may be called with different set of arguments, like overloaded functions in C++? Example:
SOURCE:POWER <SIGNAL_ID>, <VALUE>
SOURCE:POWER <SIGNAL_GROUP_ID>, <VALUE>
SOURCE:POWER <VALUE>
SOURCE:POWER <CHANNEL_N>, <ON|OFF>
Is this allowed? I have read SCPI-99 standard but can't find any direct prohibition to do this.
On the other side if this is allowed then it is not clear what should be returned by SOUR:POWER? query.
