Where there is such a directive, an explanation of the directive is provided with the option. The default number of digits is 5. The parameter blocks is a number between 6 and 62. If you omit this option, the assembler sets the size of blocks based on whether there is enough memory space or not. However, note that increasing the value of blocks reduces the amount of memory available for other assembly-language structures, such as symbol tables.
Checks syntax only, without generating an object file.
This option does not override an explicit CASE directive in the source. This option is the same as the CASE ON assembly-language directive, which also forces the assembler to distinguish between uppercase and lowercase letters. The assembler always ignores case in macro names. In all other instances the assembler ignores case, and its behavior is the same as with the preset CASE OFF directive, which forces the assembler to treat uppercase and lowercase letters the same. You can use this option on the command line to reverse the effect of one of the other case modes.
