 ;
 ; The MSHALL API is not supported!
 ;
MSHALL ; Allows application developer, in test and development environments,
 ; to change almost every field in the MSH segment.  This feature 
 ; allows the testing of the ramifications of MSH field changes, avoiding
 ; the need to edit protocol file (and other file) entries from which
 ; the MSH segment fields are derived.
 ;
 ; Call here ONLY if the full suite of variables used in MSH segment
 ; creation are available!
 ;
 ; Call method:   S HLP("SUBSCRIBER"[,n])="^^^^^MSHALL^HLCSHDR5"
 ;                D GENERATE^HLMA(.....,.HLP)
 ;
 ;                When the above HLP array is passed into the
 ;                GENERATE^HLMA API, the MSHALL subroutine is
 ;                invoked, giving the developer full control over
 ;                most MSH segment fields; even those fields not
 ;                changeable by HL*1.6*93.
 ;
 ;                See HL*1.6*93 for information about the passing
 ;                of HLP("SUBSCRIBER"[,n]) information, and the
 ;                calling of the GENERATE^HLMA API.
 ;
 ; Warning!       No audit trail (in ^HLMA or ^XTMP) is maintained.
 ;                Full responsibility rests with the application
 ;                developer.
