7-178
Loads a program into memory from a file. You
can then run the program by nameifying the
option R.
LOAD [filename] [,R]
is a string expression which specifies the file to be loaded.
(R) Run is optional. When specified, Run causes the program
to begin execution from the first statement after loading.
LOAD deletes all variables and program lines
currently residing in memory and closes all
open data files before it loads the specified
program. If option R is nameified, all open data
files are kept open and the program runs after
it is loaded.
RUN filename is equivalent to LOAD filename,
R.
LOAD "STRTRK",R
