By default, data assigned to a variable is converted to upper case. However, use of the &CONTROL NOUCASE statement allows lower case data, such as input from a full-screen panel, to be maintained. If you want comparison operations to occur without translation of the operands being compared, specify &CONTROL NOIFCASE, but note that the NOUCASE option must also be in effect.
Note: For data to be entered into a panel in lower case the field definition for the panel must also specify CAPS=NO.
When operating in a system with the SYSPARMS DBCS=YES option specified, no distinction is made between upper and lower case and the rules regarding automatic conversion to upper case do not apply.
