| :CASE | |
| Syntax | MAKE "CASE TRUE or FALSE |
| Explanation | CASE causes Logo to convert the output of the commands READQUOTE, READPROMPT and READLINE to upper case. CASE is an abbreviation for CASE CONVERSION. Other commands which read input like READCHAR always report an uppercase character, and READLIST always reports uppercase text.
When Logo loads, its CASE setting is TRUE. Procedures which are run with the LAUNCH command or by clicking a control, bitmap, or turtle, obtain their own copy of the variable. Setting the variable affects neither the global setting nor other procedures running at the same time.
