WordBASIC InStr Function Is Case Sensitive

ID: Q61960

Microsoft Word for Windows, versions 1.0, 1.1, 1.1a, 2.0, 2.0a, 2.0a-CD, 2.0b, 2.0c, 6.0, 6.0a, 6.0c

SUMMARY

The WordBASIC InStr function is case sensitive. For example, a search for the string "Test String", as in


   N = InStr(A$, "Test String")

returns a valid position number only if the string "Test String" is present in A$. "TEST STRING" and "test string" are not found by the InStr function.

To work around this problem, use one of the following:


   N = InStr(LCase$(A$), "test string")

-or-


   N = InStr(UCase$(A$), "TEST STRING")

The LCase$ and UCase$ functions return their arguments (in this case, the text of A$) in either lowercase text or uppercase text respectively, without modifying the original string. As a result, either method is effective for case-insensitive text searches.
