This afternoon I played some with the FvwmScript module as
it comes with Fvwm 2.5.11. I noticed several inaccuracies
in the documentation plus one thing that seems to be a bug.
I have included my notes below.

--- errata in the documentation ----------------------------------
1.
In the sentence:
The second part contains instructions whom are executed...
   *** change "whom" to "which"
2.
In the sentence:
Display a menu whom lets user to choose a option.
   *** change "whom" to "which"
   *** change "a option" to "an option"
3.
In the sentence:
Return the string whom is between position int1 and...
   *** change "whom" to "which"
4.
In two places in the man page we have examples with "Case Message of".
   *** change "Message" to "message" in both places because this
       is apparently case-sensitive
5.
Under the "ANATOMY OF A SCRIPT" section, the five parts of a
FvwmScript are defined.  It says: "And the last [that is, the
fifth] part contains the description of widgets."
However under the "MAIN OF A SCRIPT" section, it says: "The second
part of the script contains the description for every widget...".
   *** the "second part" should be "last part".
--- a bug -------------------------------------------------------
It appears that a "for-loop" insists that its lower index be 1.
The following does not work:
     For $i=4 To 9 Do
--- two suggestions for enhancement -----------------------------
1.
Currently we have several Get* functions, such as GetValue,
GetHilight, etc.  A GetIcon is missing.  (GetIcon id) should
return the `Icon' field of a ItemDraw or PushButton widget.
2.
It would be nice to get FvwmScript's variables to be interpreted
in all context.
For instance, if we have:
Init
 Begin
   Set $w=48
  End
then in the definition of the following widget, $w is not recognized:
Widget 3
Property
 Size       $w $w   ##### PROBLEM: we expect $w to be 48 here but it is not
 Position   10 10
 Type       ItemDraw
 Icon       mypixmap.xpm
End
