GSAM stands for

technology mainframe

Generated Sequential Access Method
Generalized Sequential Access Method
Generalized Servicing Access Method
Generalized Sequential Authendication Method

GSAM is a

technology mainframe

unordered and non hierarchical data base
sequential and hierarchical data base
sequential and non hierarchical data base
unordered and hierarchical data base

Data base access in GSAM can be done by

technology mainframe

Queries
Function calls
DL/I calls
DL/1 calls

The format of GSAM call is

technology mainframe

CALL 'CBLTDLI' USING call-func, pcb-name, ioarea
CALL 'CBLTDLI' USING call-func, Ioarea
CALL 'CBLTDLI' USING pcb-name, Ioarea
CALL 'CBLTDLI' USING call-func, pdb-name pcb-name, Ioarea

The call function name used for getting the next record is

technology mainframe

GNXT
GN
GETNEXT
GETN

The call function name used for inserting a new record is

technology mainframe

INSERT
INSRT
ISRT
INST

In GSAM we can insert records

technology mainframe

At the beginning only
At the specified position
At random position
At the end only

We can add records randomly to GSAM data sets

technology mainframe

True
False

GSAM does not allow us to

technology mainframe

add and edit the record
Add and delete the record
Modify and delete the record
insert and delete the record

GSAM records can be

technology mainframe

Only fixed length record
only variable length record
both fixed length and variable length records
only specified length record

GSAM data bases can be accessed from CICS through DL/I calls

technology mainframe

True
False

For variable length records the record length must be specified at the

technology mainframe

last 2 bytes of the record
First 2 bytes of the records
3rd and 4th bytes of the record
The record length will not be specified in the record

The format of an I/O area with control characters for the fixed length record is

technology mainframe

the data begins in byte 1
the data begins in byte 0
control character in byte 0 and data begins in byte 1
control character is specified at the end

When the call is successful the return code is

technology mainframe

0
GB
Blank
AF

When the GSAM detected a variable length record with an invalid format it returns

technology mainframe

When the RSA(Key feed back area ) for GU call is not specified it returns

technology mainframe

When there is a data management open error it returns

technology mainframe

The format of an I/O area with control characters for the variable length record is

technology mainframe

the data begins in byte 1
byte 0 and byte 1 contains 2 byte length field
byte 0 contains control character and byte 1 and 2 contains the length field
byte 0 and 1 contains the 2 byte length field and byte 3 contains control character

RSA field holds the

technology mainframe

Actual record
Address of the next record
Address of the record retrieved
Address of the previous record

When an invalid request is issued against GSAM database it returns

technology mainframe
