        Using IO_Check and IO_Result in Personal Pascal

                       September 29, 1986


If   you  have tried using IO_Check and IO_Result  (page  6-72  of 
Personal  Pascal  manual) you may have noticed that  the  compiler 
generates  an error message #104 - Undeclared Identifier.

This  is the result of an oversight during the development of  the 
compiler.   IO_Check and IO_Result are in the PASLIB library; they 
can  be used as described in the manual.   You need  only  declare 
them  as  EXTERNAL  routines before you  reference  them  in  your 
program.  An example follows:

    { Declare IO_Check and IO_Result EXTERNAL... }

    PROCEDURE IO_Check( b : BOOLEAN ); EXTERNAL;
    FUNCTION IO_Result : Integer; EXTERNAL;

    { the rest of your program follows... } 

Once you have entered these lines into your program,  you may  use 
IO_Check and IO_Result anywhere in your program.
