Use this panel to specify the compatibility modes options of the RS08 assembler.
The following image shows the Compatibility modes panel.
The following table lists and describes the compatibility mode options for RS08 Assembler.
| Option | Description |
|---|---|
| Select all (-Compat) | Check to enable all compatibility mode options. |
| Symbol prefixes ( -Compat=s) | With this suboption, the Assembler accepts "pgz:" and "byte:" prefixed for symbols in XDEFs and XREFs. They correspond to XREF.B or XDEF.B with the same symbols without the prefix. |
| Ignore FF character at line start Symbol prefixes (-Compat=f) | With this suboption, an otherwise improper character recognized from feed character is ignored. |
| Alternate comment rules (-Compat=c) | With this suboption, comments implicitly start when a space is present after the argument list. A special character is not necessary. Be careful with spaces when this option is given because part of the intended arguments may be taken as a comment. However, to avoid accidental comments, the Assembler does issue a warning if such a comment does not start with a "*" or a ";". |
| Support FOR directive (-Compat=b) | With this suboption, the Assembler supports a FOR - Repeat assembly block assembly directive to generate repeated patterns more easily without having to use recursive macros. |
| Add some additional directives (-Compat=a) | With this suboption, some additional directives are added for enhanced compatibility. The Assembler actually supports a SECT directive as an alias of the usual SECTION - Declare Relocatable Section assembly directive. The SECT directive takes the section name as its first argument. |
| Operator != means equal (-Compat==) | The Assembler takes the default value of the != operator as not equal, as it is in the C language. For compatibility, this behavior can be changed to equal with this option. Because of the risks involved with this option for existing code, a message is issued for every != which is treated as equal. |
| Support $ character in symbols (-Compat=$) | With this suboption, the Assembler supports to start identifiers with a $ sign. |
| Support additional ! symbols (-Compat=!) | The following additional operators are defined when this option is used:
Note: The default values for the following ! operators are defined:
