Compile time array is the array which is declared with all
the actual values in the program.using CTDATA

Pre run time array: It is loaded from a column of physical
file

Run time array: values are loaded in the array during
execution time

Answer / syam

You define array on "D" Specification you can load data
into a array at compile, with value entered at end of the
program is called = Compile time array.

You define array on "D" Specification you can load data
into a array at compile, with value obtained from a File is
called = Pre-Runtime Array

Arrays can be loaded with valuse during the program
execution this is called = Runtime Array

Answer / narendra

Compile Time Array:-
Array is defined in the D spec. eg
DArraymonth S 9 A DIM(3) CTDATA PERRCD(1)
Array data is defined in the last. eg
**CTDATA Arraymonth
January
Feburary
March
Pre Run Time Array:-
Array is define in the D Spec.
FROMFILE keyword is defined. eg
DARRAYMONTH S 9 A DIM(12) FROMFILE(MONTHNAME)
Array data is defined in the program described file.
T and F and record length must be defined while defining the
file in the F spec.
FMONTHNAME IT F 15 DISK

Answer / sivakumar y

small correction about pre run time array:

The file used as input must be a sequential program
described file. DURING INITIALIZATION, BUT BEFORE ANY
INPUT, CALCULATION, OR OUTPUT OPERATIONS ARE PROCESSED the
array is loaded with initial values from the file. By
modifying this file, you can alter the array’s initial
values on the next call to the program, WITHOUT RECOMPILING
the program.

It can be of keyed access path or arrival sequence. *IMMED- *IMMED description says access path is updated each time record is added or deleted from a member. - What is updating here? *REBLD - The access path is completely rebuilt each time a file member is opened. The access path is maintained until the member is closed, then the access path is deleted. - I am not able to understand this completely. Could anyone explain these more clearly? 5.What is the purpose of using activation group. I know it is a resource allocator, but other than this any other benefits of using an activation group?
