CALLED BY ^DD(1,.01,"DEL",.5,0) -- "DEL" node of FILE of FILEs (File#1) field NAME (field#.01)

lvn DIC == "^DIC"

CALLED FROM PAGE1+34^DIDH1

lvn DIC == global root of file or subfile

when double loop active

sometimes WRITE text

when loop finishes

sometimes init lvn DG == -1

sometimes init lvn X == -1

sometimes KILLs lvn W1

sometimes KILLs lvn DOPT

when loop stopped by undef lvn DIU

sometimes KILLs DDV

sometimes KILLs %F

sometimes KILLs M1

QUIT

OUTPUT VARS

sometimes inits lvn DDPT=1

always inits lvn W1 == XECUTE-able code with WRITE

always evals $ORDER(^DD(DA,0,"PT",X))

OUTPUT VARS

lvn X

always inits to ""

LOOP start with X over $ORDER(^DD(DA,0,"PT",X))

lvn DG

always inits to 0

always exits line == 0

after command=8 then == subscript of ^DD(DA,0,"PT",X, ...

DOUBLE LOOP start with DG over $ORDER(^DD(DA,0,"PT",X,DG))

Calls PD^DIDH

sometimes WRITEs

sometimes calls H^DIDH

CALLED from POINT^DIDH

INPUT VARS

lvn DA == DDnumber

lvn X == subscript of ^DD(DA,0,"PT", ...

lvn DA == subscript of ^DD(DA,0,"PT",X ...

checks if not $D(^DD(X,DG,0))

-- if field DG of file X is undefined

then KILL ^DD(DA,0,X,DG) ;; kill off this reference

then QUIT  ;; process no more

skips if $P(^DD(X,DG,0),U,2)["V"

-- if datatype of field is VARIABLE POINTER

otherwise if $P($P(^DD(X,DG,0),U,2),"P",2)-DA)

-- if datatype is a pointer and does not points to current DDnumber

TAG WR^DIDH

FALLSTRU from PD+1^DIDH

if unknown right margin in lvn IOM

then force default I/O device as IOP == "HOME"

then call ^%ZIS

if POP is true

ie fails to init home device

then QUIT subroutine

TAG WR+1^DIDH

FALLS THRU from WR^DIDH

IF lvn DDPT is defined (setup in POINT+1^DIDH)

then assume W1 is defined (also setup in POINT+1^DIDH)

then XECUTE W1 (setup as a WRITE)

then KILL lvn DDPT flag variable
