Abstract: UNITAP and UNIWRI are programs to read and write (respectively) various kinds of "foreign" magtapes on a RSTS/E system. Both are preset to default to 800 bpi, IBM SL tapes, fixed records, EBCDIC character code. The following characteristics may be selected by the user, if the default is inappropriate: 800/1600 bpi: EBCDIC/ASCII/BCD character codes; with or without tape labels: fixed or variable blocks: LRECL and block-size.

Both programs support wild-carding. UNITAP also supports the following features: dump only the first N records on the tape: dump a random N% sample of the records on the tape: invoke a user-supplied function to modify/select/reject each record; print a directory of the tape (with no output to disk).

Both programs also compile and run under BASIC-PLUS-2, for faster execution and/or larger blocksizes.

Note: HELP messages in the programs and comments in the source code.
