•

All address-typed variables except:

CBADDR

CWADDR

PROCADDR

Testing Hardware Indicators

pTAL does not have the hardware indicators—the overflow bit, the carry bit, or the

condition codes—that TAL has. Instead, the compiler emits code that supports the

$OVERFLOW, $CARRY, and condition code test operators (<, >, =, <=, >=, <>,'<', '>',

'=', '<=', '>=', '<>').

For more information, see Section 13, Hardware Indicators.
