SLICE#->AL Converts slice number to aL where data is stored.
SLICE#->OFF Converts slice number to offset where data is stored.
OFF->SLICE# Converts offset back to slice number...no error checking.
SET-SLICE# Sets to slice number on stack (from zero).
GET-SLICE# Gets the current slice number.
#USED-SLICES Number of used slices (s.here - s.first).
#FREE-SLICES Number of slices not used (s.tot - used.slices).
FIRST-USLICE To the first used slice.
LAST-USLICE To lasst used slice.
NEXT-USLICE? To next used slice if available no change if not.
returns a flag T=on next used slice, F=no change
PREV-USLICE? To previous used slice if available no change if not.
returns a flag T=on previous used slice, F=no change
NEXT-USLICE To next used slice or wraps to first used slice if on last.
PREV-USLICE To prev. used slice wraps to last used slice if on first.
FIRST-SLICE To slice number zero. (i.e. the first slice)
LAST-SLICE To slice# s.here - 1. (i.e. the last slice)
NEXT-SLICE? To next slice if available or no change if on last.
returns a flag T=on next slice, F=allready on last slice.
PREV-SLICE? To previous slice if available or no change if on first.
returns a flag T=on previous slice, F=no change.
NEXT-SLICE To next slice or wraps to slice number zero.
PREV-SLICE To previous slice or wraps to the last physical slice.
HERE-SLICE#? Next available slice# or last slice + 1 if all used.
returns flag: T=here slice available, F=all slices used
TO-HERE-SLICE To next available slice if one is available.
COPY-SLICE->SLICE Copies from slice# to slice# leaves from# untouched.
SWAP-SLICES Swaps from slice# & to slice# through temp slice#
temp slice# is overwritten.
SLIDE-> Slides from lo# to hi# count slices up.
SLICE<- Slides from lo# to hi# count slices down.
OPEN-SLICE Opens up one slice at current slice# if an unused
slice is available.
CLOSE-USLICE Closes up current slice.
Slides from current + 1 to last used slice.
CLOSE-SLICE Closes up current slice.
Slides from current + 1 to last physical slice.
INIT-SLICE Fills the current slice with zeros.
INIT-ALL-SLICES Fills all slices to zeros.
MOVE-SLICE->SLICE Moves from slice# to slice# then deletes from slice#.
->PUSH-SLICE Pushes one slice on to front (low number end) of slice
array. Does not dynamically alter the structure.
Does not push if all slices are full
PUSH-SLICE<- Pushes one slice on to end (high number end) of slice
array. Does not dynamically alter the structure.
Does not push if all slices are full
<-POP-SLICE Pops one slice off the front of the slice array.
Does not dynamically alter the structure.
Does not pop if all slices are empty.
POP-SLICE-> Pops one slice off the back of the slice array.
Does not dynamically alter the structure.
Does not pop if all slices are empty.
UROT-> Rotates the last used slice in front of the first.
UROT<- Rotates the first used slice after the last used slice.
SET-SLICE-ACTION> Puts cfa of word following on stack for use with
RUN-USLICES and RUN-SLICES.
RUN-USLICES Goes through all the USED slices and executes the
cfa on the stack for each one. Restores to the
slice coming in on when finished.
RUN-SLICES Goes through ALL the slices and executes the
cfa on the stack for each one. Restores to the
slice coming in on when finished.
