INT(32) dblnum := 147D;

rrlnum := $FLTR (dblnum); ! Return rounded REAL value

• The EpTAL compiler does not support this procedure. Use $TRIGGER (page 345) instead. (The

EpTAL compiler does allow $FREEZE as a DEFINE name.)

• Execution does not return from this call.

$FREEZE halts the processor in which its process is running and any other processors on the same

node that have FREEZE enabled.
