MUMPS Code Examples

Instructions for page
For each of these code fragments, be sure to put them in CODE tags, and note whether the code is Standard MUMPS, and if not, what MUMPS systems it works on. === Title for explanation of code purpose == NOTE: Standard MUMPS  some code 

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})
