Another in a long line of complaints about keyword inheritance. It
seems that now (though I don't recall this always having been a
problem), a wrong keyword is not flagged.
E.g.
pro testex2,b=b
print,'test2'
return
end
pro testex, a=a,_EXTRA=e
print,'test1'
help,/st,e
testex2, _EXTRA=e
return
end
IDL> testex,b=1
test1
** Structure <82441b4>, 1 tags, length=2, refs=1:
B INT 1
test2
IDL> testex,a=1,b=1
test1
** Structure <81ad99c>, 1 tags, length=2, refs=1:
B INT 1
test2
IDL> testex,a=1,b=1,c=1
test1
** Structure <8234884>, 2 tags, length=4, refs=1:
B INT 1
C INT 1
test2
This last one should have been an error in testex2! C is not a valid
keyword to testex2, but it was silently ignored. I don't think this has
always been the case. It's a real problem if you mistype a keyword, but
aren't alerted.. you may not realize that your program didn't recieve a
keyword argument. Has anyone else noticed this?

Perhaps you want:
PRO TRY, m, _extra=e
plot, m, _extra=e
END
and then:
m = bindgen(100,100)
TRY, m, thick=3

Yes I think that's I want but....
but in the procedure that I try to use this keyword seems not to run.
The compiler don't made error message but there's no evident effect of
this keyword in my plot (a map).
More simply:
if I have a _extra keyword in a procedure how can I use it?
I can use EVERY other keyword of the procedure associated to them?
Thanks
Regards,
Antonio
