The Access Method Services utility program IDCAMS is commonly used to manipulate ("delete and define") VSAM data sets. Custom programs can access VSAM datasets through Data Definition (DD) statements in Job Control Language (JCL), via dynamic allocation or in online regions such as in Customer Information Control System (CICS).
A relative record data set (RRDS) is a type of data set organization used by IBM's VSAM computer data storage system. [1]: 5 Records are accessed based on their ordinal position in the file (relative record number, RRN). [1]: 29 For example, the desired record to be accessed might be the 42nd record in the file out of 999 total.
A linear data set (LDS) is a type of data set organization used by IBM's VSAM computer data storage system. [1]: 5 The LDS has a control interval size of 4096 bytes to 32768 bytes [2] in increments of 4096.
Basic Direct Access Method, or BDAM is an access method for IBM's OS/360 and successors computer operating systems on System/360 and later mainframes. BDAM "consists of routines used in retrieving data from, and storing data onto, direct access devices." [1]: p.5 BDAM is available on OS/360, OS/VS2, MVS, z/OS, and related high-end operating ...
Calculators generally perform operations with the same precedence from left to right, [1] but some programming languages and calculators adopt different conventions. For example, multiplication is granted a higher precedence than addition, and it has been this way since the introduction of modern algebraic notation.
Casio V.P.A.M. calculators are scientific calculators made by Casio which use Casio's Visually Perfect Algebraic Method (V.P.A.M.), Natural Display or Natural V.P.A.M. input methods. V.P.A.M. is an infix system for entering mathematical expressions, used by Casio in most of its current scientific calculators.
In IBM mainframe operating systems, Basic sequential access method (BSAM) [1] is an access method to read and write datasets sequentially. BSAM is available on OS/360
In IBM mainframe operating systems, Queued Sequential Access Method (QSAM) [1] is an access method to read and write datasets sequentially. QSAM is available on OS/360 , OS/VS2 , MVS , z/OS , and related operating systems.
