; write an idl procedure, compile it and execute it.
;
; @param command {in}{required}{type=string array}
; array defining the procedure to be created. 
; each element will be a line of the created procedure.
;
; @keyword FILENAMEIN {in} {default=for_createpro.pro}
; name of the procedure to be created.
;
; @keyword KWDLIST {in} {type=vector string}
; to specify a list of keywords that must be included in the procedure 
; definition. 
;
; Warning: the string must start with a ',' 
; for example: KWDLIST=', TOTO = toto'
;
; @keyword KWDUSED 
; obsolete, please pass directly your keywords through _EXTRA
;
; @keyword _EXTRA 
; Used to pass keywords to the created procedure.
;
; @restrictions
; - is not working with functions, use <pro>createfunc</pro> instead.
; - arguments can be given only through keywords.
; - ends the procedure name with '.pro' if needed.
