* irp (indefinite repeat)
**FIXED**
* Source Debug output file including linkable object files, C64Debugger format
* Adding MERGE directive, Label Pools rewrite, TEXT data can be indexed from a string symbol
* Label Pools were destroyed after each scope so they did not work in include files which defeated their purpose. Label pools are now persistent through scopes.
* Labels reserved from label pools now distinguish between global and local. Use [.!@$] as a prefix to reserve a local label from a label pool (previously always local)
