I want to check if the option is set so I can then assign the variable flnm.

But I do not know how I can do it. I expected the -z expressions to work.

I have also tried the using -v and removed all the code after the if statement. Still same problem.

Code:
if [[ -v arg_Smirs ]]; then
  flnm="${txPath}/${flnm01a}"
elif if [[ -v arg_Capav ]]; then
  flnm="${txPath}/${flnm02a}"
elif if [[ -v arg_Igmfn ]]; then
  flnm="${txPath}/${flnm03a}"
elif if [[ -v arg_Segpi ]]; then
  flnm="${txPath}/${flnm04a}"
elif if [[ -v arg_Exads ]]; then
  flnm="${txPath}/${flnm05a}"
elif if [[ -v arg_Isemi ]]; then
  flnm="${txPath}/${flnm06a}"
elif if [[ -v arg_Cocpl ]]; then
  flnm="${txPath}/${flnm07a}"
elif [[ -v arg_file ]]; then
  flnm="${txPath}/${arg_file}"
else
  flnm="${txPath}/${flnm04a}"
fi

Solved.
Code:
elif if

Could not see it for some reason !!!
--- pdated at 01:06 AM ---

I am using [ -v arg ]; and I am wondering whether I would be better off with [[ -v arg ]];

Perhaps not, as I do not need globbing for checking existence of variables

Code:
if [ -v arg_Smirs ]; then
  flnm="${txPath}/${flnm01a}"

gst-complete-0.8

gst-complete-0.8(1)						   User Commands					       gst-complete-0.8(1)

NAME

       gst-complete-0.8, gst-complete - perform bash completion for gst-launch command lines

SYNOPSIS

       complete -Cgst-complete-0.8 gst-launch

       gst-complete [--gst-list-mm] [--gst-mm=string] [--print]

DESCRIPTION

       gst-complete-0.8 enables bash to provide context-sensitive tab completion for gst-launch command lines. See gst-launch(1) for the syntax of
       gst-launch command lines.

       You must have a version of bash that supports programmable completion. Such versions of bash provide the complete built-in command.

       gst-complete is a wrapper script that runs the latest installed version of gst-complete-X.X. For example, if both gst-complete-0.7 and gst-
       complete-0.8 are installed on your system, gst-complete runs gst-complete-0.8.

OPTIONS

       The following options are supported by gst-complete-0.8 and gst-complete:

       --help	       Display detailed usage message. You can also use -? to specify this option.

       The following options are supported by gst-complete only:

       --gst-list-mm   List found major/minor versions. This option displays the versions that are available.

       --gst-mm=string Force  major/minor  version.  This  option  enables you to specify a specific version to run, if you do not want to run the
		       default version.

       --print	       Print wrapped command line. This option displays the command that will be run, and then runs the command.

EXAMPLES

       Example 1: Generating the Registry of Available Plugins by Running gst-compprep

       Run the following command in your .bash_profile or other appropriate place:

       example% complete -C gst-complete-0.8 gst-launch

       Example 2: Running the Wrapper Script and Displaying the Command Name

       example% gst-complete --print
       /usr/bin/gst-complete-0.8

FILES

       The following files are used by this application:

       /usr/bin/gst-complete-0.Executable for bash completion for gst-launch

       /usr/bin/gst-complete   Wrapper script that runs the latest installed version of gst-complete-X.X
