146          <h3>Examples</h3><div class="preformat">
147
148 We create a structure:
149   IDL> b=get_extra(ok=111, year=[1997,1998,1999], age_capitaine=35)
150   IDL> help, b,/struct
151       ** Structure <817f4bc>, 3 tags, length=10, refs=1:
152          AGE_CAPITAINE   INT             35
153          OK              INT            111
154          YEAR            INT       Array[3]
155
156 We put this structure as a string:
157   IDL> a=strkeywd(b)
158   IDL> print, a
159       AGE_CAPITAINE=35, OK=111, YEAR=[1997,1998,1999]
160
161 Now we can use the string a to pass keywords in a function thanks to execute!!
162   IDL> test=execute('c=get_extra('+a+')')
163   IDL> help, c,/struct
164       ** Structure <817f2dc>, 3 tags, length=10, refs=1:
165          AGE_CAPITAINE   INT             35
166          OK              INT            111
167          YEAR            INT       Array[3]

189 Beware, this function has loops, ifs and cases everywhere. So it can
190 not be used by big keywords (with a lot of elements which are big
191 arrays). The input keyword must not contain Complex floatings, structure,
192 Double-precision complex, Pointer, Object reference, Unsigned Integer,
193 Unsigned Longword Integer, 64-bit Integer or Unsigned 64-bit Integer.
