Formatting Variables and Array Elements

The Variable Format (VF) command is used to format variables and array elements. The VF command is specified by:

VF m.n

where m is the number of digits to the left of the decimal point (0 thru 10) and n is the number of digits to the right of the decimal point (0 thru 4).

A negative sign for m specifies hexadecimal format. The default format for VF is VF 10.4 Hex values are returned preceded by a $ and in 2's complement.

Instruction	Interpretation
V1=10	Assign V1
V1=	Return V1
:0000000010.0000	Response - Default format
VF2.2	Change format
V1=	Return V1
:10.00	Response - New format
VF-2.2	Specify hex format
V1=	Return V1
$0A.00	Response - Hex value
VF1	Change format
V1=	Return V1
:9	Response - Overflow

Local Formatting of Variables

PF and VF commands are global format commands that affect the format of all relevant returned values and variables. Variables may also be formatted locally. To format locally, use the command, {Fn.m} or {$n.m} following the variable name and the ‘=’ symbol. F specifies decimal and $ specifies hexadecimal. n is the number of digits to the left of the decimal, and m is the number of digits to the right of the decimal.

Instruction	Interpretation
V1=10	Assign V1
V1=	Return V1
:0000000010.0000	Default Format
V1={F4.2}	Specify local format
:0010.00	New format
V1={$4.2}	Specify hex format
:$000A.00	Hex value
V1="ALPHA"	Assign string "ALPHA" to V1
V1={S4}	Specify string format first 4 characters
:ALPH

The local format is also used with the MG command.
