The above code look for a 'string' match Patchmesh
and build a array from that info.
and what I trying to do is to build a for loop by
asignment of the array.

ex.
this is the info I like to build with a for loop
        @riGeo1 = @{$riPrimGroup[0]};
        @riGeo2 = @{$riPrimGroup[1]};
        @riGeo3 = @{$riPrimGroup[2]};
        @riGeo4 = @{$riPrimGroup[3]};
        @riGeo5 = @{$riPrimGroup[4]};

so I thought about this

for ($i = 0; $i < $#riPrimGroup; $i += 1 ) {
      @riGeo$i = @{$riPrimGroup[$i]};
}

but it doesn't work, maybe a join could be used to
build the for loop and append it to the 
arrayname 'riGeo+newname'

the idea is to read in a file 'geometry data' extrate
information PatchMesh or another info and build a
ArrayName of how many PatchMesh it is find this way
I could print information about this info and build
the 'geometry' group for export to another format.
