Manipulating O/S binary files in BASIC

No direct mechanism exists for reading O/S binary files (.JPG, .MP3, and so on) into a BASIC program variable. This is due to the translation of special characters commonly found in binary files that, if not translated, will confuse or be corrupted by D3. Segment marks, attribute marks, and value marks fall into this category.

Instead, you can do the following:

1. Copy from the O/S into a D3 file using the nt_bin or unixb driver.
2. Read the item from that file into a BASIC variable using the binx driver.
3. Manipulate the hex-ASCII string in the program.
4. Write the BASIC variable out to the D3 file using the binx driver.
5. Copy the item out to the O/S using the nt_bin or unixb driver.

Example(s)

 data "(binx:hextest"
 execute \\copy nt_bin:c:/temp test.txt\\
 open 'binx:hextest' to file
 read item from file,"test.txt"
 *Manipulate item here.
 *This example replaces string for brevity.
 item = "6261FFFEFF6766"
 write item on file,"test.txt"
 data "(nt_bin:c:/temp"
 execute \\copy binx:hextest test.txt\\
