Re: Assigning a value to a DDS varlen defined field

Should the compiler not just set the length of XCVAR1 to 5 when I assign the
value 'false' if the XCVAR1 length is less then the value I want to set
using the %subst function or can someone explain why not?

Then Jon Paris wrote:
It will - but that wasn't what you did - you tried to replace a substring which by definition must already exist. The from/length values must be in range for the field in question. Until you have placed a value in the field (which you effectively did by using %Len) the %Subst can't work.

That's the way it works and since it is consistent with all other uses of %Subst that seems a realistic approach to me.



The same is true of work fields defined on RPGIV D-specs as "varying"...
