Hi ,

Please help me in the following doubts :

1) Which artihmetic operation is faster : Binary or Packed decimal
2) How to decide Which operation to choose for arithmetic .

Thanks

Binary runs rings around packed-decimal but it does have its limitations.

Does this question pertain to Assembler or PL/I, because HLL's (not so much PL/I, but definitely COBOL) can treat binary different as opposed to native Assembler.

Hello,

Once the arithmetic is done, what will be done with the resulting values?

Hi ,

In the first artimetic i have to compute some value to determine a conditional execution of routine .

Second case , I have to calculate a new value and write/print in outfile file .

Thanks

Hello,

In that case i suspect the difference will not be visable/measurable.

Remember that in order to make a binary human-friendly, it will be converted to packed and then edited.
