| cdp card punch | |
| cdp2 card punch stacker 2 | |
| 25-Apr-03 RMS Revised for extended file support | |
| 08-Oct-02 RMS Added impossible function catcher | |
| Normally, cards are represented as ASCII text streams terminated by newlines. | |
| This allows cards to be created and edited as normal files. Set the EBCDIC | |
| flag on the card unit allows cards to be read or punched in EBCDIC format, | |
| suitable for binary data. | |
