alternate case - a string processing function that returns a string argument with each letter alternated.

acase(string)

• string can be a string variable, function or literal

See also lcase, pcase, tcase, ucase

acase works with variable-, fixed-length and constant strings. The result can be assigned to a variable or fixed-length string, and passed to a string parameter or function result. If the specified string is in lowercase then acase has the same effect as ucase. If the specified string is in uppercase then acase has the same effect as lcase.

This example converts a string to alternate case, then to lowercase and finally to uppercase using acase.
