Convert special characters to lower ASCII strings

Dealing with legacy systems, you need to convert your data all day long. For example, if you have to print UPS labels and send data to UPS via the PLD 0200 interface, you must not use any special characters you have within your international address data. This routine converts these characters to their best¹ lower ASCII representation. For example 'Ä' and 'Æ' get converted to 'Ae'. Usage:

DEF VAR cAnsiString AS CHAR CASE-SENSITIVE NO-UNDO.
DEF VAR cAsciiString AS CHAR CASE-SENSITIVE NO-UNDO.
ASSIGN cAnsiString = 'Ää'.
RUN makeCleanAsciiString.p (INPUT cAnsiString, OUTPUT cAsciiString).
MESSAGE cAnsiString '==>' cAsciiString VIEW-AS ALERT-BOX.

Result: 'Ää==>Aeae'
