ICC Ignore case when comparing text

ICC is a logical format. The standard setting is NICC (false).

ICC specifies that case is to be ignored when testing or comparing text. It applies to all text comparisons.

For example:

dm $mwhich=$9/’A’,’B’

with ICC this will pick up ’r;a’ and ’r;b’ as well as ’r;A’ and ’r;B’.

if $9-10/’ox’,

with ICC this will pick up ’r;OX’, ’r;Ox’, ’r;oX’ as well as ’r;ox’.
