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.
