Hello all,

I've go some legacy code I'm trying to update and it looks like:

; Read text header from file
; until 'end header' reached.
;-----
line = ''
header = ''
repeat begin
readf, unit, line
if (n_elements(header) eq 0) then $
begin
header = line
endif else $
begin
header = [header,line]
endelse
endrep until (strtrim(line,2) eq 'end header')

;-----
; Close file.
;-----
close, unit & free_lun, unit

;-----
;Get relevant info from the header.
;-----
dda_header.file_id = $
strtrim( get_keyword( header, 'file ID'), 2)

This code is circa 95 and it's balking at the get_keyword() function. So my
questions are two:
1) Did previous versions of IDL have a get_keyword() (I'm 5.3 now)?
2) It's clear this code is simulating a HASH with Arrays, does IDL 5.3 have
native hash support of some kind?

Thanks,
