Hi,
COMP can occupy from 2 bytes to 8 bytes.
For example,
S9(1-4) COMP will occupy 2 bytes.
S9(5-9) COMP will occupy 4 bytes.
S9(10-18) COMP will occupy 8 bytes.
Normally COMP is used for subscripts in tables.
COMP-1 will occupy 4 bytes - single precision
COMP-2 will occupy 8 bytes . double precision
COMP-1,COMP-2 are used in calculations with floating type variables with precision required.
Thanks
