Notes:

Choose at least one option.

Default: NOCOMPAT
Abbreviations: CPAT(CASE, NOCASE, LIT, NOLIT, MC, NOMC, SYSL, NOSYSL,TRS,NOTRS) / NOCPAT
MC as a COMPAT abbreviation means "MACROCASE", but for PCONTROL, means "MCALL".
Parameter of ACONTROL statement: You can specify the COMPAT (or NOCOMPAT) option as a parameter of the ACONTROL statement. For further details, refer to the "ACONTROL instruction" in the HLASM Language Reference.
CASE: Instructs the assembler to maintain uppercase alphabetic character set compatibility with earlier assemblers. It restricts language elements to uppercase alphabetic characters A through Z if they were so restricted in earlier assemblers.
NOCASE: Instructs the assembler to allow a mixed-case alphabetic character set.
LITTYPE: Instructs the assembler to return "U" as the type attribute for all literals.
NOLITTYPE: Instructs the assembler to provide the correct type attribute for literals once they have been defined.
MACROCASE: Instructs the assembler to convert (internally) lowercase alphabetic characters (a through z) in unquoted macro operands to uppercase alphabetic characters (A through Z).
Note: A quoted macro operand begins and ends with an apostrophe. Operands containing an apostrophe that do not begin and end with apostrophes are considered unquoted.
NOMACROCASE: Instructs the assembler not to convert (internally) lowercase alphabetic characters (a through z) in unquoted macro operands.
SYSLIST: Instructs the assembler to treat sublists in SETC symbols as compatible with earlier assemblers. SETC symbols that are assigned parenthesized sublists are treated as character strings, not sublists, when passed to a macro definition in an operand of a macro instruction.
NOSYSLIST: Instructs the assembler not to treat sublists in SETC symbols as character strings, when passed to a macro definition in an operand of a macro instruction.
TRANSDT: Instructs the assembler to extend use of the translation table, as specified by the TRANSLATE assembler option, to any C-type character Self-Defining Terms.
NOTRANSDT: Instructs the assembler not to translate any C-type character Self-Defining Terms.
NOCOMPAT: Instructs the assembler to allow lowercase alphabetic characters a through z in all language elements, to treat sublists in SETC symbols as sublists when passed to a macro definition in the operand of a macro instruction, and to provide the correct type attribute for literals once they have been defined.
