Hello All,

=20

Requirement: Dynamically increase the number of arguments to EXEC task
based on the number and name of the file in a directory.

=20

For example a sample directory contains the following files with
extension "*.rod" (Number of rod files in the "src" directory
dynamically change):=20

C:\src> dir /b *.rod

Details.rod

Info.rod

Summary.rod

=20

Right now, I'm hard coding the file names in arguments to EXEC task in
the following way

<target name=3D"erdpro">

            <condition property=3D"erdpro.client.dir" value=3D"C:\Program
Files\Actuate8\eRDPro\bin" >

              <os family=3D"windows"/>

            </condition>      =20

=20

            <echo> Compiling ROD files. Please wait...</echo>

            <exec dir=3D"${erdpro.client.dir}"
executable=3D"${erdpro.client.dir}/erdpro" >

                        <arg value=3D"-b"/>

                        <arg value=3D" Details.rod" />

                        <arg value=3D" Info.rod" />

                        <arg value=3D" Summary.rod" />

            </exec>

</target>

=20

Above target is good when I hardcode the files to the "arg". I want to
dynamically add "arg" values based on the number and name of the file. I
want to know how I can achieve my requirement. (Should I use marcodef?
If so how?)

=20

Any help is highly appreciated.

=20

Thanks,

Mohan
