Purpose:
Performs a command for a set of files.
Syntax:
for % % c in set do command
(for batch processing)
for % c in set do command
(for interactive processing)
Comments:
To avoid confusion with the %0- %9 batch parameters, the vari-
able
c can be any character except 0,1,2,3, ... ,9.
set is ( item* )
This command sequentially sets the % % c variable to each
member of set, and uses the variable to evaluate command. If a
member of set is an expression involving a wildcard (* or ?), then
the variable is set to each matching item from the disk. In this
case, only
one such item is in set, so the command ignores any
item
other than the first.
Examples:
The following example binds the variable %f to files ending with
*.asm in the working directory.
for %%f in ( *.asm ) do masm %%f
It then executes a command of the following form:
masm filename
Filename could be anyone of the following:
invoice.asm
receipts.asm
taxes.asm
The following example binds the variable %f to the files named
report, memo, and address; it then deletes each of these files:
for %%f in (report memo address) do del %%f
c
