This has the effect of inserting the filename you have given (D:PROG1) into
the variable "$1" in the SUBMIT file. The result would be to display a direc-
tory of the disk in drive B: and then load BASIC from drive B: before running
the BASIC program PROG 1 on the disk in drive D: and then showing the BASIC
files on drive D:.
There can be any number of variables in the SUBMIT file, and you must en-
sure that the filenames you give are in the correct order to be substituted at
the appropriate time. For instance, if you have a SUBMIT file TESTING .SUB
containing the following commands:
DIR
$1
DIR
$2
STAT
$3
DIR
the command you give to execute it with the .COM files TESTA, TESTB and
TESTC in that order should be:
C>SUBMIT TESTING TESTA TESTB TESTC
so that they are substituted in the correct order.
Some CP/M programs (PIP for example) use the "$" character in their sub-
commands, and if this will mean they will be interpreted as variables. Conse-
quently care must be taken as follows to overcome this by adding an extra "$"
whenever the subcommand uses a "$". SUBMIT will then ignore the first one
and then treat the second one as normal. For example to insert the command
to cause STAT to set all files on disk A: as Read/Only use:
STAT A:*.* $$R/O
WARNING:
The SUBMIT program writes a temporary file when it runs. This file will
be written to drive A: and
if
the disk is write protected, an error will be
generated and you will not be able to proceed further. Similarly
if
the
RAM disk A: is set to zero bytes a "DIRECTORY FULL" error will be
generated.

1.1. Creating a SUBMIT file in BASIC

~
Since the PX-S is not supplied with the CP/M program ED, and you may not
W"J
r
have a wordprocessor program, BASIC may be the only means of creating a
., r
'~..
SUBMIT file. This can be done very simply by creating a sequential text file
and writing the commands to it as data. Chapter 5 of the BASIC Reference
;, I
~
Manual gives details of creating text files. For instance, the series of commands
~ 1 given above could be put into the file called START.SUB with the following
'VJ ( "
"Ill'
I
.~
e~
I
/~
,.\
.~

' - ' / I

program:
10 OPEN "0", # 1, "D:START.SUB"
20 PRINT # 1, "DIR D:"
30 PRINT # 1, "STAT D: *. * "
40 PRINT # 1, "ERA D: * .BAK"
50 PRINT # 1, "PIP E:
=
D: * .BAS"
60 CLOSE
70 END
Or, put another way:
10 OPEN "0",
#
1, "D:START.SUB"
20 READ A$
30 IF A$
=
"END" THEN 60
40 PRINT
#
1, A$
50 GOTO 20
60 CLOSE
70 END
S0 DATA "DIR D:", "STAT D: *. *
'~'ERA
D: *
.BAK'~'PIP
E:
=
D: *.B
AS'~'END"
Either of these programs will create a file called START.SUB containing the
commands you want which can then be executed from the CP/M prompt by
typing:
C>SUBMIT d:START
You could even write a utility program in BASIC to allow you to create a SUB-
MIT file at any time by putting in the commands as you go and then storing
them in a .SUB file of your choice:
10 INPUT "Type in drivename and filename ";F$
20 OPEN "0", # 1, F$
+
".SUB"
30 INPUT "Enter command or END ";A$
