A BASIC program is very capable of introducing a virus into a computer system, and it need not be something as obvious as a poke statement and a bunch of data statements. One very old technique is to package an assembly program with a BASIC program, and save it as a BASIC file. This is done by writing the BASIC program, writing the assembler program, loading the assembler program, adjusting the End Of Progam pointers, and just saving it like a normal BASIC program. Then the program need only execute a call statement once. This technique was used on the Program Line Editor program by Beagle Brothers, however many years ago. -- Michael J Pender Jr Box 1942 c/o W.P.I. greyelf@wpi.bitnet 100 Institute Rd. greyelf@wpi.wpi.edu Worcester, Ma 01609 I wrote SHELL, please send bug reports to me.
