+        subroutine ftgkys(iunit,keywrd,strval,comm,status)

+C       read a character string value and comment string from a header record 
+C
+C       iunit   i  fortran input unit number
+C       keywrd  c  keyword name   
+C       OUTPUT PARAMETERS:

+C       written by Wm Pence, HEASARC/GSFC, June 1991
+C       modified 6/93 to support long strings which are continued
+C       over several keywords.  A string may be continued by putting
+C       a backslash as the last non-blank character in the keyword string,
+C       then continuing the string in the next keyword which must have
+C       a blank keyword name. 
+C       Modified 9/94 to support the new OGIP continuation convention
