MUMPS Code to iterate over every global

NOTE: this is NON-STANDARD MUMPS. Known to work on GT.M

SET GBLNAME="^%" FOR  SET GBLNAME=$ORDER(@GBLNAME) QUIT:GBLNAME=""  DO Something(GBLNAME)

MUMPS Code to iterate over every value of the first subscript of the global ^XTMP

NOTE: Standard MUMPS Note: the following code immediately stops if there are no subscripts to ^XTMP

SET SUB="" FOR  SET SUB=$ORDER(^XTMP(SUB)) QUIT:SUB=""  DO Something(SUB)

MUMPS Code to iterate over every FileMan File

NOTE: Standard MUMPS

S FILE=0 F  S FILE=$O(^DIC(FILE)) Q:FILE'=+FILE  D Something(FILE)

MUMPS Code to iterate over Data Dictionary Number of every FileMan File & Subfile

NOTE: Standard MUMPS

S DDNUM=0 F  S DDNUM=$O(^DD(DDNUM)) Q:DDNUM'=+DDNUM  D Something(DDNUM)

Getting the {K} closed root for a Data Dictionary Number

NOTE: Standard MUMPS Given a Data Dictionary number generates a closed root with the "variables" expressed as as the three letters: "{K}" Note this allows one to iterate through all of the "constant" parts of root using $PIECE and two argument $LENGTH. The result CANNOT be used directly with indirection i.e. @ROOT@(something) until the {K} text is replaced with either a constant or a variable.

S RESULT=$$ROOT^DMSQU(ddnum)

Example: PATIENT File #2 has a Field #1900 the "APPOINTMENT" multiple that is in DDNUM 2.98

MUMPS> W !,$$ROOT^DMSQU(2.98)

^DPT({K},"S",{K})
