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

INPUT VARS

DA == DDnumber

$ORDER(^DD(DA,0,"PT","")) -- what files point at this one.

OUTPUT VARS

sometimes inits lvn DDPT=1

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

TAG POINT^DIDH

FALLSTHRU from POINT^DIDH

INPUT VARS

lvn DA

$ORDER(^DD(DA,0,"PT",

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

OUTPUT VARS

lvn X

always inits to ""

always exits line ==""

after command=5 then == subscript of ^DD(DA,0,"PT", ...

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

IF undef lvn DIU
