If MAXFILES is executed within a program , memory pointers will
be altered. This can cause problems with GOSUB, GOTO , and
other instructions. If you need to execute a MAXFILES command
within an Integer BASIC program , do so using an EXEC file
(discussed later).
If you need to execute a MAXFILES command in an Applesoft
BASIC program , the command should be the first statement in
the program and should be preceded with a Control-D character
as illustrated below :
100 PRINT CHR$(4); " MAXFILES 6"
EXEC
The EXEC command allows for the execution of an EXEC file.
Configuration
EXEC filename, [ Rx , Sx , Vx, Dx]
R indicates the relative field number within the EXEC file where
execution is to begin . RO is the default value which causes
execution to commence at the beginning of the EXEC file . If R1
was specified, execution would begin with the file 's second
record.
When the EXEC command is executed, the indicated EXEC file is
first opened . Then, the line specified by the R parameter is read
and
executed as if it had been entered via the key board in the
immediate mode .
If the line is a valid program line , it will be stored in memory--just
as if it had been entered in the immediate mode . If the line is a
command such as LIST , CATALOG , SAVE , or RUN, it will be
executed.
