Add an "@" before the procedure. This was changed recently to make the 
compiler consistent with both itself and the documentation.

In TP you have:

procvar(para1,para2,...) = call procedure (or just "procvar" if it has 
no parameters)
@procvar = contents of procvar
@@procvar = address of procvar
procvar := procedure/function = assign address of procedure/function to 
procvar


In FPC you have:

procvar(para1,para2,...) = call procedure (or just "procvar()" if it has 
no parameters)
procvar = contents of procvar
@procvar = address of procvar
procvar := @procedure/@function assign address of procedure/function to 
procvar


I think the FPC syntax is more logical.
