Simple String Problem

[rana]

Code: Select all

@echo off
set string=Hello
set ab = Batch
set b = Programming
if [%string%]==[] echo "String is empty"
if [%string%] NEQ [] echo String is %string%
echo %ab% %b% 

The code should print out

Code: Select all

String is Hello
Batch Programming

... but instead it is printing out something else... i am attaching an image please have a look..

Hi rana,

it's a problem of your code formatting.
In batch you can't use spaces in a SET expression, without side effects.

The correct syntax is

Code: Select all

SET var=content
or even better, to protect against invisible trailing white spaces
SET "var=content"

You used set ab = Batch, this sets a variable with the name ab<space> to the content <space>Batch
