[mkgmap-dev] regex to remove leading 0

Fri Oct 11 09:39:12 BST 2013

the example doesn#t work:

Error: (points:396): Invalid arguments to EQUALS: VALUE 
(${rcn_ref|subst:^0+~>}) and EXISTS (rcn_ref=*)e: Error: (points:396): 
Invalid arguments to EQUALS: VALUE (${rcn_ref|subst:^0+~>}) and EXISTS 
(rcn_ref=*)

for command: set rcn_ref='${rcn_ref|subst:^0+~>}'

shy ain't it working for rcn_ref?
