Jon,

Note that if the last character is a '/' it would throw an error, unless it's MONITORed.

This is way simpler I think - not tested though.

filename = %subst( %trimr(input) : ( %scanR( '/': %trimr(input) + 1 );

%trimR not needed if the input is varchar.

Simplified it would look like this:

tempVarchar = %trimR( input );

filename = %subst( tempVarchar : ( %scanR( '/': tempVarchar ) + 1 );

I _think_ that example may have originated with Barbara Morris when %ScanR came out.

Methinks that LastPos is something you wrote, but failed to include?

//===============================================================
p LastPos...
p b
d pi 10i 0
d pString 256 const varying
d pWhat 1 const

// Pass in a string and this returns the rightmost position
// of the 'What' (2nd) parameter. Could be . or a / or anytin.
//===============================================================
d len s 10i 0
d spos s 10i 0
d pos s 10i 0
d lastpos s 10i 0

len = %len(%trimr(pString));
spos = 1;
//---
dou (pos=0) or (spos>=len);
pos = %scan(pWhat :pString :spos);
if pos> 0;
spos = pos + 1;
lastpos = pos;
endif;
enddo;
//---
return lastpos;
