This will cause the DOS Support program to be executed. This pro-
gram will relocate itself into the top of the user memory, where it
will coexist with programs which are entered later. DOS support will
not need to be reloaded until the computer is reset. The following
special symbols, once implemented, will simplify the entry of disk
commands.
USING THE DOS SUPPORT SYMBOLS: > and @
Once DOS SUPPORT is implemented, preceding disk commands with
PRINT#lfn or enclosing them in quotation marks is no longer required: precede
the disk command with either the greater than symbol (>) or the at-sign (@). The
examples in this manual use the > symbol.
Examples:
>I0 is the same as PRINT#1,"I0"
>S0:FILE1 is the same as PRINT#15,"S0;FILE1"
The OPEN statement is NOT required before a statement.
The > symbol can also be used to load a diskette directory. Normally the
directory is loaded with LOAD"$dr",8 but this command destroys any program
you might have in memory. When you use the > symbol, the directory is printed
directly to the screen, thus preserving the data in the computer's memory.
Example:
>$0 means display the entire directory
>$0:Q* means to display all the files on the drive
