I am trying to do a simple comparison. At the 6th character of a string, I am trying to determine if it contains the integer "1". There seems to a plethora of examples on how to perform more complex matches by issuing the command "help about_reg*" in powershell or consulting http://msdn.microsoft.com/library/az24scfc.aspx. Nothing is evident for my instance in all these examples and I cannot seem to derive if from the examples given. I have tried -match "…1*" but when I peform the -match "…2*" it gives me the same result. Please let me know how I can specify a match on a particular integer which would be the 6th character in a string.

Since you are looking for a specific character at a specific location in a string, just treat the string like an array:
PS C:\Windows> $str = "abcde1ghi"
PS C:\Windows> $str[5] -eq "1"
True
PS C:\Windows> $str[5] -eq "2"
False

Just for reference, a regex for that might look like this:
$string = 'abcde1ghi'
$string -match '^.{5}1'
