Addressing Floating Point Files

The addressing format for floating point data files is shown below.

Programming Floating Point Values

The following table shows items to consider when using floating point
data.

Table 2:

Format

Explanation

Ff:e

Floating Point file

File number

The valid file number range is from 8 (default) to 255.

Element delimiter

Element number The valid element number range is from 0…255.

Examples:

F8:2
F10:36

Floating Point File 8, Element 2
Floating Point File 10, Element 36

IMPORTANT

These rules do not apply to the SCP instruction. See page 210 for the rules for
that instruction.
