   The best program to accomplish this is called barrel written by
Moshe Braner.  It has several functions to allow capturing text or
screen dumps to a file.  It is TSR (terminate & stay resident) which
may or may not be what you originaly wanted, but it is good and it
works....

  Not likely...  The example you gave will bomb miserably...  The
parameters you gave for Pexec are in the wrong order and ignore an
important pecularity in the Pexec call (the command tail is a Pascal
style string, not a C style string).

  The correct order for Pexec parameters is:
	Pexec mode:	zero is fine
	Program name:	standard C string format
	Command tail:	a pointer to a Pascal style string (a string 
			with the character count in the first byte!)
	Environment:	A pointer to an environment block or NULL if
			you want to use the default environment.

  Thus, a corrected version would read:

static unsigned char tailbuf[255];
....
tailbuf[0] = strlen(tail);
strcpy(tailbuf+1,tail);
Pexec(0, "A:\\folder1\\folder2\\program.ttp", tailbuf, (char*)NULL);
