Guardian Application Conversion Guide DCT Limit Extension Addendum—527418-001

1-6

Short-Term Change

For each call to the GETDEVNAME procedure:

1. Read the changed description of the parameter ldevnum in the Guardian

Procedure Calls Reference Manual. If necessary, change your program to

accommodate this change.

2. Ensure that the parameter ldevnum is treated as unsigned (16 bits), specifically:

Change all uses of signed arithmetic operators and signed relational operators

to the equivalent unsigned operators.

Change all uses of standard functions that require signed inputs (such as

$DBL, $MIN, and $MAX) to the unsigned equivalents (such as $UDBL, $LMIN,

and $LMAX).

3. If your program uses a negative number other than -1 for ldevnum, change that

negative number to either -1 or the equivalent unsigned number (65,535).

For information about signed and unsigned operators and standard functions, see the

TAL Reference Manual and the TAL Programmer’s Guide.

GETPPDENTRY

For each call to the GETPPDENTRY procedure, make either the Recommended

Change on page 1-6 or the Short-Term Change on page 1-6.

Recommended Change

Replace the call to the GETPPDENTRY procedure with a call to the D-series

procedure PROCESS_GETPAIRINFO_.

Short-Term Change

Ensure that index is treated as unsigned (16 bits), specifically:

•

Change all uses of signed arithmetic operators and signed relational operators to

the equivalent unsigned operators.

•

Change all uses of standard functions that require signed inputs (such as $DBL,

$MIN, and $MAX) to the unsigned equivalents (such as $UDBL, $LMIN, and

$LMAX).

For information about signed and unsigned operators and standard functions, see the

TAL Reference Manual and the TAL Programmer’s Guide.
