EXAMPLE
The	following example illustrates the use of a carriage control
a	trigger.
TRIGGER1=\,1,X'F1'		/\ Look for Skip-to-Channel 1
TRIGGER2=ð,5ð,'ACCOUNT:'		/\ Find account number
TRIGGER3=3,75,'PAGE 1'		/\ Find page 1

In this example, TRIGGER1 instructs ACIF to scan every record, lookin the occurrence'F1of' inX the first byte. After ACIF locates a re
