Non-DOS Scripting
Use the SysSleep function whenever you need a time delay in Rexx scripts. SysSleep is available in OS/2's (native) RexxUtil module and in Patrick McPhee's RegUtil module for 32-bits Windows.
Use the Sleep command for time delays in KiXtart scripts.
Use WScript.Sleep, followed by the delay in milliseconds in VBScript and JScript (unfortunately, this method is not available in HTAs).
The following batch code uses a temporary VBScript file to generate an accurate delay:
@ECHO OFF
REM %1 is the number of seconds for the delay, as specified on the command line
> "%Temp%.\sleep.vbs" ECHO WScript.Sleep %~1 * 1000
>> CSCRIPT //NoLogo "%Temp%.\sleep.vbs"
>> DEL "%Temp%.\sleep.vbs"
