Intrinsics Descriptions

Descriptions of the Intrinsics Available in MPE/iX

Alphabetical listing of all Intrinsics available.

ABORTSESS

NM and CM callable.

Enables a program to abort a speciﬁed job or session from the system.

I16V I32V I16A

ABORTSESS(

jsid,jsnum,jsstatus

);

ACTIVATE

NM and CM callable.

Activates a newly created process, or a process suspended with the SUSPEND intrinsic.

Requires process handling (PH) capability.

I16V U16V

ACTIVATE(

allow

);

ADJUSTUSLF

NM and CM callable.

Adjusts directory space in a USL ﬁle by moving the start of the information block forward

(or backward) on a user subprogram library (USL) ﬁle, thereby increasing (or decreasing)

the space available for the ﬁle directory block. The overall length of the ﬁle does not

change. This intrinsic is intended for programmers writing compilers. A USL contains CM

object code and is meaningful only in the CM program development process.

I16 I16V I16V

uslferror

:=ADJUSTUSLF(

uslfnum,adjustment

);

ALMANAC

NM and CM callable.

Returns the numeric date information for a date returned by the CALENDAR intrinsic. The

returned information is year of century, month of year, day of month, and day of week.

U16V U16A I16 I16 I16 I16

ALMANAC(

date,daterror

yearnum,monthnum,daynum,weekdaynum

);

ALTDSEG

NM and CM callable.

Reduces the storage required by the extra data segment when moved into main memory

and expands storage as required, allowing for a more efﬁcient use of memory. Data

segment management (DS) capability is required. Data segment management (DS)
