The CopyVar command copies the contents of one variable into another, without evaluating the contents.
Example.
Input:
| a:=c |
| c:=5 |
| CopyVar(a,b) |
Output:
| c |
then:
Output:
| 5 |
Changing the value if c will also change the output of
b, since b contains c.
Input:
| c:=10:; |
| b |
Output:
| 10 |
