RE: Moving Char field to Numeric field right justified

Hi everybody

Thanks for your inputs / suggestions / solutions. Though I would love to
work on RPG-IV, my customer should say so. Thus even if it means working
harder, I need to work in RPG-III :).
I did some work-around and got this. Here is what I did.

CUSIDQ is the input char field with numeric values left justified and CUSIDN
is the output field with numeric values right justified.

E                    ARY1        9  1
E                    ARY2        9  1

C                     ELSE

Hi Barbara,
I'm not sure if I have an example, but I may have been thinking of this:
  %dec('   $1,234.50' : 7 : 2)
And I realize it is the $ that's the issue (along with the commas) not the
leading blanks.

%DEC and %INT have the same rules with respect to "clean".  Do you have
an example where leading blanks cause a problem with %DEC?
