pTAL Reference Manual (G06.24+, H06.09+, J06.03+)

The EpTAL compiler supports no pTAL privileged routines except $TRIGGER.
Table 59 pTAL Privileged Routines
DescriptionProcedure
Converts a standard address or a relative extended address to an absolute
extended address
$AXADR
Executes an I/O operation$EXECUTEIO
Freezes (halts) the processor in which its process is running and any other
processes on the same node that have FREEZE enabled
$FREEZE
Halts the processor in which its process is runningVOLATILE Attribute
Stores cause and status information from an I/O interrupt$INTERROGATEIO
Locks one page of memory$LOCKPAGE
Returns the base and limit of the current extended segment$READBASELIMIT
Replaces $FREEZE and $HALT, which are available only for code generated for
the TNS/R architecture
$TRIGGER
Unlocks one page of memory$UNLOCKPAGE
Writes a segment-page-table entry$WRITEPTE
Type-Conversion Routines
A type-conversion routine converts its argument or arguments from one data type to another data
type.
