dealing with arguments [message #71119]

Hello,

In this call:

proname, mode, s1, s2

s1 is necessary if mode=1; s2 is necessary if mode=2; and both s1 and
s2 are necessary if mode=3.

If mode=1, s2 can be simply omitted, but if mode=2 then the user would
still need to provide a s1, even though it will not be used, just
because 3 numbers are needed in the calling sequence in order to
define s2. Is there a way to avoid entering s1 when mode=2 while still
making IDL understands that the second number in the call refers to
s2? I hope this makes sense. Thank you!
