number can be replaced with the wildcard character &, in which case the calculator will search ports 0 through 2, and then main memory for the named backup object.
| A library object must be detached before it can be purged from the HOME directory. | |
| Neither a library object nor a backup object can be purged if it is currently “referenced” internally | |
| by stack pointers (such as an object on the stack, in a local variable, on the LAST stack, or on an | |
| internal return stack). This produces the error Object in Use. To avoid these restrictions, use | |
| NEWOB before purging. (See NEWOB.) | |

PUSH | Command |
|
| |
Type: |
|
| ||
Description: | Saves the current status of the flags, and the current directory path. This allows the user to change | |||
| the flags or the directory path, then restore them all with the command POP. PUSH is equivalent | |||
| to saving the results of the commands RCLF and PATH, but it saves them in a stack from which | |||
| the most recently saved values are recovered by POP, with no need to use named variables. The | |||
| flags and the path are stored in the CASDIR directory, as a list of lists, in the variable | |||
| ENVSTACK. |
|
| |
Access: | …µPUSH |
|
| |
Input: | None. |
|
| |
Output: | Item 1: In Algebraic mode the command returns NOVAL. | |||
