<P><FONT SIZE=2>I'm not sure if I understand you, but this should work. If you make a constant </FONT>
<BR><FONT SIZE=2>array like shown in your code then what you get _is_ an array of char*. Maybe </FONT>
<BR><FONT SIZE=2>there's another reason why the initialization fails ?</FONT>
</P>

<P><FONT SIZE=2>==================================</FONT>

<P><FONT SIZE=2>Yes, the code that was listed _does_ work. =) But it assumes that you know the projection parameter ahead of time and hence, can hard code them.</FONT></P>
<P><FONT SIZE=2>My question revolves around the situations when you _do not_ know what is the projection and its parameters ahead of time.</FONT></P>
<P><FONT SIZE=2>My approach would have been to dynamically allocate memory to char ** for an array of strings.</FONT>
</P>
<P><FONT SIZE=2>But when you call sizeof(), it returns the number of bytes for the pointer and _not_ the sizeof() the array of string pointers.</FONT></P>
<P><FONT SIZE=2>So essentially I'm trying to define the input and output projection and their parameters at run-time.</FONT>
</P>
<P><FONT SIZE=2>I hope this provides more clarification.</FONT>
