It's a fairly complicated library routine which puts the output of a VB script into an array and processes the array like this.

Code:
:: process each service
:: HTCMD is internal HEAD or TAIL
:: filter is a pipe to grep for specified info
do i=0 to %lastindex by 7 | d:\gnu\sort.exe %sortargs %filter | %htcmd /n %nshow | tee %tmpfile

    set name=%s[%i]        & set /a i+=1    
    set pid=%s[%i]        & set /a i+=1    
    set display=%s[%i]    & set /a i+=1    
    set wmistart=%s[%i]    & set /a i+=1    
    set ktime=%s[%i]    & set /a i+=1    
    set utime=%s[%i]    & set /a i+=1    
    set wset=%s[%i]
    set cpu=%@eval[(%ktime + %utime) / 10000000 =3]
    set workset=%@eval[%wset / 1024**2 =1]
    
    echo %@tformat[%wmistart]%@format[8,%pid]   %@format[10,%cpu]  %@format[8,%workset]  %@format[-%longest,%name]%@if[%verbose == 1, %display,]

enddo
 
The problem seems to be with TAIL. In this command,

Code:
do i=0 to %lastindex by 7 | d:\gnu\sort.exe %sortargs %filter | %htcmd /n %nshow | tee %tmpfile

%htcmd is either TAIL (the default) if HEAD (both internals). If I specify HEAD I get the correct output; with TAIL I don't.

Code:
