Hello,

"Type MATH_ACCUM
length As Integer ' # of MATH_INTs
Sign As String * 1 ' "?" means non-numeric, invalid data
pad As String * 1
MInts(1 To 5) As Integer
End Type ' MATH_ACCUM
"

LOCAL lcMathAccum
lcMathAccum = BINTOC(theLenght,"RS") + ; && thelength = some numeric variable 
"?" + ; && or whatever other single char makes sense
" " && another single character ..

&& append MInts array ..
FOR xj = 1 TO theLength
 lcMathAccum = lcMathAccum + BINTOC(theInts[xj],"RS")
ENDFOR

&& pad to full length (26 bytes) if less than 5 MInts were appended ..
lcMathAccum = PADR(lcMathAccum,26,CHR(0))

&& the functioncall ...

Regards
Christian
