The user-defined formatter used is:
fmtst 123 "z261 f6:2 i[Battery ]z257 f6:1z273"
An example of typical output from this formatter string might be:
Temperature 27.23 Battery Voltage 12.6
Here is a description of what each part of the formatter does:
fmtst 123 – This is the command word for storing the formatter sting in area
123.
z261 – This outputs the fixed string ‘Temperature’.
space –This outputs an ASCII space.
f6:2 – This takes the value from location 1 and outputs it. The output field has a
total width of 6 characters; 2 decimal places are available within the field.
space – This outputs an ASCII space.
i[Battery ] –This outputs the word between the brackets [ ].
z257 – This outputs the fixed string ‘Voltage’.
space – This outputs an ASCII space.
f6:1 – This takes the value from location 2 and outputs it. The output field has a
total width of 6 characters; 1 decimal place is available within the field.
z273 – This outputs the fixed string ‘CrLf (carriage return line feed)’.
