These are additions to FOCAL W, of 8/68, for both 4 and 8K

systems. Assembly language listings are included as Appendices.

Appendix l gives the simple patch required to permit group

numbers to go up to 31.99 rather than 15.99. This may be

useful only with 8K. Included in Appendix l is the symbol

table used by PAL-3 for all the additions.

Appendix 2 gives a simple routine which on repeated calls

turns the echo on and off. This simplifies "read-in" of data

tapes if only a low speed reader is available. The routine

uses the DXS function slots in the tables. Systems with scopes

will have to provide a change. The routine occupies unused

locations in the floating point package.
