My windows batch says: “72 was unexpected at this time.”

Question

My batch file below, creates an .avs file for given list of parameters and then runs a program which takes this .avs file as an argument and does this multiple times in a for loop.

But when I run my batch file, it prints 72 is unexpected at this time. , 72 is value of one of the parameters. The .avs file is not created and the program is not executed.

My batch file and its output on command prompt with REM @echo off is below.

My batch file:

REM @echo off

set RawSource26=C:\_rawsource26\RawSource26.dll
set avsFile=.\temporary.avs
set avs2yuv=C:\_avs2yuv\avs2yuv.exe

set width=1024
set height=768
set cropLeft=72
set cropTop=0
set cropRight=0
set cropBottom=0

(for %%v in (%views%) do (
  @echo. 2> %avsFile%
  @echo LoadPlugin("%RawSource26%") >> %avsFile%
  @echo Crop(RawSource(".\renderOut\%video%_%%v_synth.yuv", %width%, %height%, "i420"), %cropLeft%, %cropTop%, %cropRight%, %cropBottom%) >> %avsFile%
  %avs2yuv% %avsFile% -raw -o .\avsOut\%video%_%%v_synth_avs.yuv
  (for %%r in (%rates%) do (
    @echo. 2> %avsFile%
    @echo LoadPlugin("%RawSource26%") >> %avsFile%
    @echo Crop(RawSource(".\renderOut\%video%_%%v_%%r_synth.yuv", %width%, %height%, "i420"), %cropLeft%, %cropTop%, %cropRight%, %cropBottom%) >> %avsFile%
    %avs2yuv% %avsFile% -raw -o .\avsOut\%video%_%%v_%%r_synth_avs.yuv
))))

REM del %avsFile%

循环中的)实际上不是“关闭”，而是部分echo需要“转义”-然后用^)替换，否则批处理将不转义- )作为close of block
