If you know the size at declaration, you can say it as a fixed length table. Variable length tables vary in size depending on the value of another variable.

6) Why Picture clause should not specify in comp1 and comp2?
|
The use of Picture clause is to specify the type, size and format. But for Comp-1 & 2, the size is 4B & 8B respectively. The type is Hexadecimal in floating point. The format is +0.9999E+99. If you know the size, type & format, then there is no need to specify.
