This package adds support for the formats in the IEEE 1687 spec. It provides a new major mode icl-mode that includes basic syntax highlighting, indentation, and imenu support for the Instrument Connectivity Language (ICL). Also sets up .pdl files to better support the Procedural Description Language (PDL) extensions.
To add a subset of the PDL keywords to tcl-mode call the icl-add-pdl-keywords function:
(with-eval-after-load 'tcl
(icl-add-pdl-keywords))
