TOP                    PSAM/DAPDB Commands                    TOP



NAME
     top, up, down - stack navigation commands

SYNOPSIS
     top
     up
     down

DESCRIPTION
     The top, up, and down  commands  select  procedures  on  the
     stack.  The  top  command selects the procedure at the stack
     top, the up command selects the procedure one  place  higher
     in the stack than the current procedure and the down command
     selects the procedure one place lower in the stack than  the
     current procedure.

     If the selected procedure is a FORTRAN-PLUS procedure and if
     the  relevant  diagnostic  information is available then the
     file in which the procedure is defined is selected. Further-
     more the current line is set to the currently executing line
     in that procedure. If the selected procedure is an APAL pro-
     cedure the current instruction is set to 0.

     The up and down commands cannot be used if the current  pro-
     cedure is not on the stack.
