Library Functions -- $%PRODUCE^STRING

Approved for inclusion in a future ANSI M[UMPS] language standard as part of the library for String Handling.

This function returns a translated version of the value of its parameter.

This function could be used to reduce multiple separators to single ones:

; Two blanks will be reduced to a single one
SET SPEC(1,1)=" ",SPEC(1,2)=" "
; translate all relevant separators into blanks
SET X=$TRANSLATE(X,"!?,.;:()"," ")
; and reduce multiple blanks to singletons

A soundex algorithm for English names:

1. Remove non-alpha and convert lower case to upper case
2. Examine first letters
PH --> F
CE --> S
KN --> N
WR --> R
C --> K
3. Ignore all other vowels (A, E, I, O and U)
4. Then replace
MP --> M
ST --> S
DG --> D
TCH --> CH
GHT --> HT
5. Then make the following equivalent
B, F, P and V
C, G, J, K, Q, S, X and Z
D and T
M and N
6. Finally, remove multiple consecutive occurences of the same character

 SET LOW="abcdefghijklmnopqrstuvwxyz"
 FOR I=1:1:5 SET C(I,1)=$PIECE("PH C CE KN WR"," ",I)
 FOR I=1:1:5 SET C(I,2)=$PIECE("F. K S. N. R."," ",I)
 FOR I=1:1:5 DO
 . SET C(I,1)=$PIECE("MP ST DG TCH GHT"," ",I)
 FOR I=1:1:5 DO
 . SET C(I,2)=$PIECE("M. S. D. CH. HT." ",I)
 FOR I=1:1:26 DO
 . SET C(I,1)=$CHAR(64+I,64+I)
 . SET C(I,2)=$CHAR(64+I)
