^LOCKREC

This procedure excludes other external openers from accessing a record at the current

position.

The syntax, condition code settings, and considerations regarding this procedure are the

same as the counterpart in the Guardian Procedure Calls Reference Manual.

MAKE_PROCESS_HANDLE_NULL_

This procedure creates a null process handle.

processhandle output

INT .EXT:ref:10

is a pointer to the buffer to be set to the value of a null process handle (-1 in each

word).

^MYTERM

This procedure provides a task with the object name of its corresponding SU or LINE.

Use the GET^TASK^NAME procedure to get the object name of another task’s SU or

LINE.

To get the name of the home terminal for the GDSX process, call the Guardian

MYTERM procedure. MYTERM does not suspend the calling task.

length returned value

INT:value

is the length in bytes of the SCF object name. If the SU or LINE is unconverted, the

value returned is always 24 bytes. If SU or LINE is converted, the value returned is

always the length of the object name, with a maximum of 32 bytes.

object-name output

INT:ref:12

is the SCF object name (not the access name), whether the object was configured by

SCF, or the object was not configured explicitly and the object name was derived by

TSCODE from a device name. This SU or LINE name is taken from the variable

CALL MAKE_PROCESS_HANDLE_NULL_ ( processhandle ); !

length := ^MYTERM ( [ object-name ] !

,[ filenum ] ); !
