Parsing command lines

[Bhaskar G]

Dear All,

In my makefile I have a target to create
a text file. My requirement is something like this. 
I would like to generate the file with
10 words in each line. I tried defining a function as follows

define WRITE_TO_FILE
@i=1;j=$(MAXWORDS);\
while [ $$i -lt $(words $(1)) ]  ;
do \
echo $$i $$j;\
BG=$(wordlist $$i,$$j,$(1));\
i=`expr $$i + $(MAXWORDS)` ;\
j=`expr $$j + $(MAXWORDS)` ;\
done
endef

When I run gmake I get the following
error.

common.mk:1009: *** non-numeric first
argument to `wordlist' function: '$i'.  Stop.

With $(MAXWORDS) set to 10 I get the
following output if I remove the line starting BG=
1 10
11 20
21 30
31 40

Any ideas on how do I get around this
problem?

Thanks & Regards,
Bhaskar
