Test gsub on strong regex
rgx1 = '[abc]'	typeof(rgx1) = 'regexp'
rgx2 = '[abc]'	typeof(rgx2) = 'regexp'
Test gsub() a strong regex
rgx1 = '[abc]'	typeof(rgx1) = 'regexp'
rgx2 = '[aec]'	typeof(rgx2) = 'regexp'
Test value not found in regex
rgx1 = '[abc]'	typeof(rgx1) = 'regexp'
Test gsub on numbers
v1 = '12345'	typeof(v1) = 'number'
v2 = '12345'	typeof(v2) = 'number'
v1 = '12345'	typeof(v1) = 'number'
v2 = '12x45'	typeof(v2) = 'string'
Test value not found in number
v1 = '12345'	typeof(v1) = 'number'
Test gensub on regex
a = @/abc/	typeof(a) = 'regexp'
