 segofftolong()      Read a long value from a segment/offset address
------------------------------------------------------------------------------
 Declaration
   memory.hdr

 Syntax
   func long segofftolong extern
   param value uint uSegment, ;
         value uint uOffset

 Arguments
   uSegment is a segment address.
   uOffset is an offset address.

 Return
   A long value.

 Description
   This function returns the long located at the specified memory address.

   The function is included for compatibility with earlier Force versions.
   Use the ptr() data type in conjunction with the & and * operators for
   directly writing to explicit memory addresses.

 Example
   #define EXAMPLE_MEMORY
   #include example.hdr

   proc Test_segofftolong
   vardef
      long        gVar
      ptr( long ) pMem
   enddef
   gVar := -998877
   ? gVar                      // access long variable directly
   // access long variable using function calls
   ? segofftolong( segmentvalue( gVar ), offsetvalue( gVar ) )
   pMem := &gVar               // access long variable using pointer
   ? *pMem
   endproc

   proc main
   Test_segofftolong()
   endproc
