symbolToTypeCode

 

 

Overview

The symbolToTypeCode function returns the Integer type code of the type name specified.

Usage

The symbolToTypeCode function returns the Integer type code of the type name specified.

The AIS system stores information in Words which contain a declared type. For the Lisp assembler programmer, the symbolToTypeCode function allows the access and reference of declared types in Words. For instance, the following code uses the symbolToTypeCode function to check that the argument is really of the specified type.

(defun foo(Number:x)
  regs:(n)
  (vmregLoadDeclType x n)
  (if (<> (symbolToTypeCode Number:) n) then (error "Bad type passed as argument"))
  true)

 

Syntax

Expression:

(setq typeCode (symbolToTypeCode typeName))


Arguments Name Type Description
Argument:typeName String Symbol Text The symbolic name of the type whose Integer code is to be returned.
Argument:typeCode Integer Returns the typeCode, as an Integer, of the symbolic type name specified.

Returns:

typeCode
