Re: Strange behavior w/%editc()

You can easily circumvent this problem by coding as follows:

c                   eval      headdesc = Center('Fixed Model FY ' +
c                              %subst(%editc(fiscalYr -
1:'X'):%len(%editc(fiscalYr - 1:'X') - 4) :40)

So if the expression %editc(fiscalYr - 1:'X") returns 02001, the %len will
be 5.  Subtracting 4 from %len starts the substring in position 2.  Thus you
should get
    Fixed Model FY 2001
as I think you want.
