$title unloadIdx - checking execution restrictions (uldidx02,SEQ=623)

$onText
Check basic operation of execute_unloadIdx.  We expect to write only
parameters whose indices are counting numbers, i.e. 1, 2, 3, ...
Check for:
  - non-counting-numbers in the universe : OK
  - non-counting-numbers in domain: rejected
  - domain not starting with 1: rejected
  - any gaps in domain: rejected
  - writing special values: OK for eps, undf, inf, NA
  - writing special values: acronym rejected
