surely something is amiss

[__John_L.]

I thought I understood the benefits of using a legacy, stable technology for simple tasks. I'm executing this DOS command:

test.bat test Policy:

while the contents of test.bat are:

@ECHO ON
SETLOCAL EnableDelayedExpansion
SET RESULT=%2
IF '%RESULT%' == 'Policy:' SET RESULT=0
SET CHK=%RESULT:~0,16%
SET RC=%RESULT:~-10%
ECHO %RESULT% %CHK% %RC%
IF '%CHK%' == 'An error occurred' (
   ECHO %RC% 
   EXIT /B %RC%
)
REM

and I get this:

Z:\WindowsSandbox\tools>SETLOCAL EnableDelayedExpansion

Z:\WindowsSandbox\tools>SET RESULT=Policy:

Z:\WindowsSandbox\tools>IF 'Policy:' == 'Policy:' SET RESULT=0

Z:\WindowsSandbox\tools>SET CHK=0

Z:\WindowsSandbox\tools>SET RC=0

Z:\WindowsSandbox\tools>ECHO 0 0 0
0 0 0

Z:\WindowsSandbox\tools>IF '0' == 'An error occurred' (

Z:\WindowsSandbox\tools>ECHO 0
0

Z:\WindowsSandbox\tools>EXIT /B 0

Z:\WindowsSandbox\tools>

Why does the IF compare result in the error exit? Thanks in advance for any clarity you can provide.

What results were you expecting that you did not get?
