The CONVERT function can perform many transformations on a string. These include removing spaces, case conversion and deleting characters. One of the most important options available to the user is the ability to ignore strings enclosed in quotes. So it is possible to request an entire string is converted to uppercase, except for those words in quotes. Two other possible uses of the function are to remove all spaces from a string. This may be useful if you prompt a user for a filename. Another use might be the removal of all but numeric characters. Multiple options can be passed to the routine. Some will turn others off and take precedence over others. (If you would like to suggest other conversion routines to be added to CONVERT, please contact us and let us know your ideas.)
