read/store array from lowest to highest eg 1 - 11

NDog · 06 Jan 2018 01:32

Is there a way to sort digits in an array from lowest to highest eg 1 - 20, WITHOUT resorting to prefixing a leading 0 so they are both same number of digits? This is because my range may vary somewhat, and I don't want to have to write extra logic to deal with prefixing 0's etc. I understand that variables are text, however I'm sure someone here has a simple work around.

eg

set _x_1=value
set _x_10=value
set _x_2=value
set _x_[10]=value
set _x_[11]=value
set _x_[1]=value
set _x_[2]=value
set _x_[3]=value

values are displayed in that order, if using the set command

for /f "usebackq tokens=2-3* delims=_=" %g in (`set _x_ 2^>nul`) do (echo %g&echo %h)

If I want to call the values on the array, I would use a command as above, however it is not sorted by numerical order.

?

As you said, such values are sorted in that way if using the set command, so the solution is not use set to process the array elements, but a for /L command:

for /L %%i in (1,1,20) do echo !_x_[%%i]!

Of course, this method requires setlocal EnableDelayedExpansion command at beginning of the program.

Hi Aacini

Thanks, its a simple tip but works great.
EnableDelayedExpansion not required if you call a sub

@echo off&cls
for %%a in ("%~dp0\.") do set _parentdir=%%~nxa
title %_parentdir%

. . . .

Well, yes, but call command is less efficient than using Delayed Expansion, so I used to not use call to achieve a double expansion, excepting in certain cases...

Anyway, your call example is wrong. You inserted three percent-signs at end, but the right number is two:

:sub_install <index>
  :: set variables
  set _index=%~1
  call set _fPath=%%_fPath_[%_index%]%%
  if not defined _fPath goto :eof
  call set _swtch=%%_swtch_[%_index%]%%
  call set _regKy=%%_regKy_[%_index%]%%
  call set _regDN=%%_regDN_[%_index%]%%
  call set _regDV=%%_regDV_[%_index%]%%
  . . . .

Also, it has no much sense to duplicate the value of %~1 parameter into _index variable just to use its value. You may directly use the parameter in each case:

:sub_install <index>
  :: set variables
  call set _fPath=%%_fPath_[%~1]%%
  if not defined _fPath goto :eof
  call set _swtch=%%_swtch_[%~1]%%
  call set _regKy=%%_regKy_[%~1]%%
  call set _regDN=%%_regDN_[%~1]%%
  call set _regDV=%%_regDV_[%~1]%%
  . . . .
