in reply to Perl and paths...again :-(

It may be on your OS that $ENV{LD_LIBRARY_PATH} needs to be set before your process is launched. So either set the values and re-exec your program, or set the values from a shell script.

BEGIN { if(! $ENV{RELAUNCH}) { $ENV{RELAUNCH}=1; $ENV{ORACLE_HOME}="/export/home/riedward/oraclient"; ... exec $0 => @ARGV; }; };

[Lady_Aleena]: I might have to go with options instead of a straight list.
[Discipulus]: if more than 3 go for named variables LA
[Lady_Aleena]: Discipulus, it is at 2 now, but with what I am thinking about, it could go to 3. However, only 1 is needed. The second and third are optional.
[shmem]: straight list or named parameters - that depends on whether (and how many) optional arguments you have
[Discipulus]: if so a plain list is ok, imho
[Lady_Aleena]: shmem, I already have the plugin installed, just not active.
[shmem]: if you have 1 optional argument, place that at the end of the list. If you have more, go for named parameters.
[Lady_Aleena]: 1 manditory, 2 optional.
[Discipulus]: my ($need,$opta,$optb ) = @_; .. if $opta..
[shmem]: all else leads to trouble, even if the third argument depends on the existence of the second. That may become brittle.
