How do i get my batch script to use a command in recursive dir?

Question

example 1

@echo off  
for %%a in (precomp.exe) do set pc=%%~fa  
for /r %%a in (*.pcf) do (  
  pushd %%~dpa  
  echo [%pc% -r %%~nxa]  
  %pc% -r %%~nxa 
  popd 
)

When i run the bat i get precomp.exe is an unknown command I have precomp in the folder with the script. But it will only work if i copy precompt to every sub directory and every folder that contains a .pcf file

Tried a different approach using 2 scripts

script1   

for /r %%i in (*.pcf) do call sr2 "%%~pi" "%%i"   
script 2  
pushd %1                 
precomp -r %2    
popd        

Both scripts work but only if i copy precomp into Ever folder and all sub folders. Please help as i know there must be away to make the script use the precomp in the folder with the script

Answer 1

You can temporarily modify the PATH environment variable to include the path of precomp:

e.g.:

setlocal
set PATH=%PATH%;%~dp0
for /r %%i in (*.pcf) do (
    pushd "%%~pi"
    precomp -r %%i
    popd
)

or use the path of precomp directly:

for /r %%i in (*.pcf) do %~dp0\precomp -r %%i
