asm (reserved word)
Accesses the built-in assembler.
Syntax
asm
AssemblerStmt <Separator AssemblerStmt>
end
where
- AssemblerStmt is an assembler statement
- Separator is a semicolon, a new-line, or a Pascal comment
Remarks
When placing multiple assembler statements on a single line, separate them with semicolons. Multiple assembler statements on separate lines do not require a semicolon.
In an asm statement, a semicolon does not indicate that the rest of the line is a comment. Comments must be Pascal style, using { and } or (* and *).
Register Use
The rules of register use in an asm statement are the same as those of an external procedure or function.
An asm statement must preserve these registers:
BP SP
SS DS
An asm statement can freely modify these registers:
AX BX
CX DX
SI DI
ES Flags
On entry to the asm statement, the built-in assembler knows only the BP, SP, SS, and DS registers; it can assume nothing else about register contents.
