PRCVUTSC ;WOIFO/DST - Convert non-formatted string ; 2/11/03 4:52pm
;;5.1;IFCAP;**81**;Oct 20, 2000
;Per VHA Directive 10-93-142, this routine should not be modified.
;
CONV(STR,ACT,SC) ;
;
; Initial data for HL7, HL() array, will be used in this routine.
; Such as HL("ECH"), HL("FS")...
;
; Input:
; STR - A string to be convert
; ACT - Action, E - from escape sequences to special char
; C - from special char to escape sequences
; SC - String of special character used in this HL7 message
; SC char 1 - Field separator
; char 2 - Component separator
; char 3 - Repetition separator
; char 4 - Escape sequence character
; char 5 - Subcomponent separator
;
; Output:
; STR1 - A converted string
