Using Report Generation Functions

If you use the to_bcd function:
$D:0 = TO(10)
The value 10 converts to:
0000 0000 0001 0000
Definition: To convert an expression from BCD to its binary.
Abbreviation: F
Format: F (<expression>)
Description: The from_bcd function performs the opposite operation to the
to_bcd function. It converts expression to a 32 bit BCD number and returns
the binary representation.
Example using the from_bcd function:
If you enter:
F($D:0)
If decimal file 0 contains the BCD value (0000 0000 0001 0000). The
from_bcd function converts $D:0 to the binary bit pattern.

In this chapter, you read about the functions that you can use to tell the
1775-S4B what to do. Functions must be accompanied by a command for
proper execution. Report generation supports two types of functions:
Input access functions give you the capability of entering characters into
a procedure during procedure execution.
Format conversion functions give you the capability of expressing
values in binary or binary coded decimal format.
The next chapter describes factors that affect 1775-S4B scanner execution
time.
