You can specify constants with either of two syntax schemes: the scheme used for specifying decimal, octal, or hexadecimal constants (but not binary constants) used in the assembler (see Accessing Assembly Language Constants, Character String Constants, or the scheme used for integer constants in C syntax.

Examples:

Format Decimal Octal Hexadecimal
Assembler format 32 40q 020h
