Sets an existing variable in the current context, reports variable value.
bob fred
Associations
- Is the default command for the 'global' context.
- Does not have its own command name in 'global' for console or script.
Arguments
- name - name for variable to set
- value (optional) - the value to set. If no value, then prints value if exists.
Details
Can be used to set or report a value for an existing variable. Will fail if variable does not already exist.
This command behaves like a combination of 'var' and 'set', but will never create a variable:
- varedit - never creates, sets anytime value exists
- var - creates and sets only if not exist
- set - creates and sets any time
Examples
Default values
- 'bob' without a value. Variable 'bob' doesn't exist, and 'bob' is not the name of anything else.
> bob Unknown: bob
- Tries to set variable 'bob' to 'fred'. Fails as 'bob' does not exist.
> bob fred Unknown: bob
- Using the 'set' command to create the variable 'bob' and set to 'fred'.
> set bob fred
- Same as the first example, but now 'bob' exists.
> bob
'bob' is 'fred'
- Try to set existing 'bob' to 'james', value changes.
> bob james
> bob
'bob' is 'james'
