OpenTag reserves a space in the API for a Forth-based virtual programming language. Forth is a message-oriented, virtual programming language framework. “DASHForth” is a yet-to-be-defined implementation of Forth that is intended to support a library specifically relevant to OpenTag and DASH7 Mode 2. The ALP ID for DASHForth is 0x04.
As DASHForth has not been defined or implemented at the time of writing (03-2012), this article has little to discuss other than the fact that there is space reserved for DASHForth. The name “DASHForth” is an intended pun.
