It's the sequence of a system which decides the equivalent numeric value for each character typed in keyboard and also the procedence b/w characters.
In PC, ASCII is the default collating, while in Mainframe EBCDIC is the default. [/quote]

HGH-VALUES refers the highest value in collating sequence (X'FF'). Low calue refers the lowest value in collating sequence. (x'00')

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.
