Registers, Objects, and Tables
A register is a place to store data such as chromatograms and signals. The
ChemStation uses pre-defined registers such as ChromReg for chromatograms
and SpecReg for spectra. The chromatograms and spectra are objects in the
registers. If you load a data file containing signals A, B, and C; the ChromReg
register will contain three objects. To access data for a specific signal, specify the
number of the object in square brackets after the name of the register. For
example, ChromReg[2], accesses the second object in ChromReg.
A register is made up of a contents list, a header and one or more objects. Each
object has a header, a data matrix and possibly one or more tables.
In this exercise, you will learn how to obtain information stored in the pre-defined
registers and objects.
Registers
1) Get the contents of the register as follows: Type on the command line
Contents$=RegCont$(ChromReg) <enter>
Print Contents$ <enter>.
2) To find out how may objects are in a register, type:
Size=RegSize(ChromReg)<enter>
Print Size <enter>
3) To delete the register as well as the contents, type:
DelReg ChromReg <enter>
