7. 
Press the "Variable" and "Number 123.456" softkeys if you want to
engrave a any number in a certain format.
The format text <#.###,_VAR_NUM> is inserted and you return to
the engraving field with the softkey bar.
 The place holders #.### define the digit format in which the
number defined in _VAR_NUM will be engraved.
For example, if you have stored 12.35 in _VAR_NUM, you can
format the variable as follows.
Entry Release Meaning
<#,_VAR_NUM> 12 Places before decimal point
unformatted, no places after the
decimal point
<####,_VAR_NUM> 0012 4 places before decimal point,
leading zeros, no places after the
decimal point
< #,_VAR_NUM> 12 4 places before decimal point,
leading blanks, no places after the
decimal point
<#.,_VAR_NUM> 12.35 Integer and fractional digits not
formatted.
<#.#,_VAR_NUM> 12.4 Places before decimal point
unformatted,
1 place after the decimal point
(rounded)
<#.##,_VAR_NUM> 12.35 Places before decimal point
unformatted,
2 places after the decimal point
(rounded)
<#.####,_VAR_NUM
>
12.3500 Places before decimal point
unformatted,
4 places after the decimal point
(rounded)
If there is insufficient space in front of the decimal point to display the
number entered, it is automatically extended. If the specified number
of digits is larger than the number to be engraved, the output format is
automatically filled with the appropriate number of leading and trailing
zeroes.
Instead of the decimal point you can also use a blank.
Instead of _VAR_NUM you can use any other numerical variable (e.g.
R0).
7. Press the "Variable" and "Variable text" softkeys if you want to take
the text to be engraved (up to 200 characters) from a variable.
The format text <Text, _VAR_TEXT> is inserted and you return to the
engraving field with the softkey bar.
You can use any other text variable instead of _VAR_TEXT.
