# System Parameters

'MC' | Maintain Case

## Description

Maintains the case for variable, directives and line labels in program listings.

#### Note:
The case setting is affected by the 'LC' and 'LD' system parameters.

## Default

Off - Variable names, directives and line labels are maintained in uppercase.

## See Also

'LC' List Variables in Lowercase
'LD' List Directives in Lowercase

## Example

10 ThisIsFirst=10
20 THISISFIRST=20
list
10 ThisIsFirst=10
20 ThisIsFirst=20

Once 'MC' is set, the first instance of a variable will establish the case setting for all subsequent uses. To change the case of a variable name, all references to the variable must be removed, and the program must be saved and reloaded.
