Program Signatures
'This program example demonstrates how to request the program text signature (ProgSig =
Status.ProgSignature), and the
'binary run-time signature (RunSig = Status.RunSignature). It also calculates two
'executable code segment signatures (ExeSig(1), ExeSig(2))
'Define Public Variables
Public RunSig, ProgSig, ExeSig(2),x,y
'Define Data Table
DataTable(Signatures,1,1000)
DataInterval(0,1,Day,10)
Sample(1,ProgSig,FP2)
Sample(1,RunSig,FP2)
Sample(2,ExeSig(),FP2)

7.7.1.8 Use of Multiple Scans
CRBasic example Use of Multiple Scans (p. 181) shows how to use of multiple
scans. Some applications require measurements or processing to occur at an
interval different from that of the main program scan. Secondary, or slow
sequence, scans are prefaced with the SlowSequence instruction.
