Model Program
Buffer_Name is made up of
data item name
data item name
data item name
data item name
Indicates that a data structure is being used. Buffer_Name
is the name given to the structure, and data item name is
the name given to the individual parts of that record.
BEGIN MAIN LINE Indicates the beginning of the main body of the program.
BEGIN ROUTINE Indicates the beginning of a routine.
CALL procedure Calls the specific TurboIMAGE/XL intrinsic or internal
procedure to be used in this particular portion of the
routine, and specifies the values for each parameter.
CALLED BY Refers to that portion of the program which called the
routine.
CALLS Specifies the TurboIMAGE/XL intrinsic (library
procedure) or the internal program procedure called by the
routine. Note that the intrinsics are listed in the order in
which they are used in the routine; as a result, some may
be listed more than once. Note that the mode for each call
is also shown.
DISPLAY Displays any specified data.
END LOOP Indicates the end of an iterative block.
END MAIN LINE Indicates the end of the main body of the program.
END ROUTINE Indicates the end of a routine.
ERROR CHECKING If error found, calls a routine that checks the contents of
the status array to determine what action to take.
EXIT LOOP condition Indicates the condition which terminates an iteration.
Not_Used_Parm Indicates a dummy parameter when a particular intrinsic
call does not use a specific parameter.
OBJECTIVE States the purpose of each routine.
OBTAIN ←user input Allows the user to enter the required information
interactively.
OBTAIN parameter←value Indicates the assignment of a value to a parameter.
NOTE For Pascal programmers only: Note that parameters cannot be
odd-byte aligned.
RETURN Transfers control to the beginning of the iterative block in
which it is used.
START LOOP Indicates the beginning of an iterative block.
