Functions

0 EXPAND. Inserts spaces into a program to make it more readable. It does not touch spaces within REMs or inside quotes.
1 COMPRESS. The opposite of the above.
2 REMDEL. Same as 1, but also removes all REM lines.
3 RENUMBER. Renumber lines starting at 10 in increments of 10. The starting number can be changed by DOKE 3709,X and the increment changed by DOKE 3720,Y. Undefined line references are renumbered /999/ and may be located using the find command. Any renumbering errors are liable to corrupt the program.
4 INKEY2. The keyboard status is returned as the variable assigned to the USR call. This has a repeat action as long as the key is depressed.
5 INKEY1. As above but with no repeat action. Both 4 and 5 return 0 if no key is depressed.
6 FIND. On calling you are prompted with F? You may enter the functions you wish to find, either alphabetic or numeric or a combination of both, terminated by an ‘ENTER’. The lines containing the data required is listed on the screen N lines at a time, where N has been set by the LINES command. Default is 5.
7 SAVES. Save a string array.
8 LOADS. Reloads a string array.

Conclusion

The documentation is poor. Operation and use are good. Shame there is no LINK function instead of INKEY2. Overall very good value for money.

The tape is available from A. Watkins, 12, Merton Close, Maidenhead, Berks. Price 6.00.
