Hello,

I would like to know how to make the condition for an "if" allowing %%i to
be an integer only or go to exit.

Thanks in advance.
Cheers

Try testing the VariableContents for equality with +VariableContents,
this test is treated as True if the VariableContents are a numeric integer.

This demo shows the syntax, and uses ECHO commands for
illustration (you could replace them with GOTO commands to
to route flow to :EOF). The FOR statement tests four sample
tokens to report which are integers:

@ECHO OFF
FOR /f "tokens=1-4" %%A IN ("1.5 2x text 1001") DO (
IF %%A EQU +%%A ECHO %%A is a integer
IF %%B EQU +%%B ECHO %%B is a integer
IF %%C EQU +%%C ECHO %%C is a integer
IF %%D EQU +%%D ECHO %%D is a integer
)

====End cut-and-paste (omit this line)
