Code Issues Proposed changes

Make declared variables global

Browse Source 
When variables use the 'declare' directive, it is by default a local
variable. While other variables have global scope.

For example:
   declare -A AN_ARRAY   # local in scope
   foo=1                 # global in scope

This causes errors to occur as some of the variables will be local only
and others will be global.

Update the code, as appropriate, so that variables using the 'declare'
directive also include the '-g' flag to have them also be global. Not
every instance of a declared variable has been updated.
