GETMSG(IEN,MSG) ;
;Description: given the message ien=MSGIEN (required), it returns the MSG array containing information about the message, defined below.
;Input:
; IEN - the ien of the message in file 773
;Output:
; Function returns 1 on success, 0 on failure
; MSG (pass by reference, required) These are the subscripts returned:
; "BATCH" = 1 if this is a batch message, 0 if not
; "CURRENT MESSAGE" - defined only for batch messages - a counter used during building and parsing messages to indicate the current message. It will be set to 0 initially.
; "BODY" - ptr to file 772 which contains the body of the message.
; "CURRENT LINE" - a counter used during building and parsing of
; messages to indicate the current line within the message. For
; batch messages where each message within the batch is stored
; separately, this field indicates the position within the current
; individual message
; "HDR" - the header segment, NOT parsed, as a sequence of lines HDR(i)
; "IEN" - ien, file 773
