var

Reads and writes variables or C-expressions.

Syntax

var

var <var-spec> [-np] [-s|-ns] [%<conv>]

var v: [-np] [-s|-ns] [%<conv>]

var <var-spec> [-s|-ns] [%<conv>] =<value>

Options

The following table lists and defines options of the var command.

Table 1. `var` Command-line debugger command - Options
Command	Description
`[none]`	No option is equivalent to "var v:".
`v:`	If this option appears with no <var> following it, then all variables pertinent to the current scope are printed.
`<var>`	Symbolic name of the variable to print. Can be a C expression as well.
`-np`	Don't print anything to the display, only return the data.
`-s\|-ns`	Specifies whether each value is to be swapped. For memory, specifies whether each cell is to be swapped. With a setting of -ns, target memory is written in order from lowest to highest byte address. Otherwise, each cell is endian swapped. If unspecified, the setting "config MemSwap" is used.
`%<conv>`	Specifies the type of the data. Possible values for <conv> are given below. The default conversion is set by the radix command for memory and registers and by the config var command for variables.
`%x`	Hexadecimal.
`%d`	Signed decimal.
`%u`	Unsigned decimal.
`%f`	Floating point.
`%[Q<n>]F`	Fixed or Fractional. The range of a fixed point value depends on the (fixed) location of the decimal point. The default location is set by the config command option "MemFixedIntBits".
`%s`	ASCII.

Examples

The following table lists and defines examples of the var command.

Table 2. `var` Command-line debugger command - Examples
Command	Description
`var myVar -s %d`	Displays the endian-swapped contents of variable myVar in decimal.
`var myVar =10`	Changes the value of variable myVar to 16 (0x10).
