_closeEditEqu will update imathptr2 and the size word in the program,
then calls _CLOSEPROG.  if you call _CLOSEPROG first, it will chop off
the end of the program.

_setupEditEqu also calls _EDITPROG, but i think it sets a flag and will
ignore the second call.

i've never managed to get _detok to work properly, but since closeeditequ
uses the editcursor as the end of the buffer, you might try calling
_bufToBtm before closing the buffer.

there's another call named _setEditDetok.  i don't know how it works, but
it might prove useful.

you shouldn't need to call these directly:

_EDITPROG - expand program
  input:
    ade -> start of program
    _PTEMP_END-_FREE_MEM = bytes to add
  output:
    bytes added at end of program
    _P_IMATHPTR1 = start of var (storage area :P)
    _P_IMATHPTR2 = original end of var (free space added here, update!!)
    _P_IMATHPTR3 = new end of var (byte after)
    _P_IMATHPTR4 = bytes after var (block moved size)
    all regs destroyed

_CLOSEPROG - collapse program
  input:
:    _P_IMATHPTR1 = ptr start of var storage area
    _P_IMATHPTR2 = original end of var (byte after end, update!!)
    _P_IMATHPTR3 = new end of var (byte after used)
    _P_IMATHPTR4 = bytes after var (block moved size)
  output:
    _P_IMATHPTR3+_P_IMATHPTR4 bytes
    moved to _P_IMATHPTR2
    all regs destroyed?
