SHELL argument

[2BASIC]

Is it possible to compute the argument part of the SHELL command?

For example SHELL $A

where $A is a string variable computed elsewhere in the program eg DIR/p or DIR >>dir.txt

Could you rephrase that? I'm not sure of what you are asking.
Do you mean that if say:

a$ = "chkdisk"
SHELL a$

would it run chkdisk? Yes.

Please be more specific with your question.

And make sure you put the dollar sign AFTER the variable name, like QBASICKING did, and not before like in the example in your original question.

a$ = "DIR >>dir.txt:
SHELL a$

will append a directory listing to a file named dir.txt.

Spot-on response thanks, to both qbasicking and trollacious......real problem I guess is too much rust in my memory Bring back Fortran and punched cards.
