Structured Assembly Language Programming

• What is structured assembly language programming
  ?
• It is a programming methodology that aids in the
  development of complicated software with a
  minimum amount of error.

3
Flow Chart

• Flow chart is a flow design structured programme
  to solve the problems.
• Flow chart also helps to correct and modify
  developed software.
• There are symbols to use in designing flow chart
  to ease programmer. These symbols consists of
  following process
• Process, predefined process, input/output,
  decision, connector and terminal.
• Table shows examples of symbols to use in flow
  chart programme.

Structured Assembly Language Programming

• Process Symbol
• Shows any type of process in a programme.
• Predefined process
• Usually contains the name of the subroutine or
  module.
• Input / output symbol
• Whenever data are input to the programme or
  output from the programme.
• The input / output symbol usually shows the type
  of data and the directioin of data flow.
• Decision symbol
• Computer systemss most capability is ability to
  make decisions.
• The symbol asks question to determine the
  direction of programme sequence.

Structured Assembly Language Programming

• Connector
• Eliminates crisscrossed connecting lines in
  complicated flowcharts.
• Ease in understanding the developed programme.
• Terminal Symbol
• Programmes all start somewhere and require a
  symbol to show where they start.

Flow chart

• Flow chart example mean calculation of a set of
  numbers

If-Then-Else

• The solution.

10
Repeat-Until

• Allows process to be executed or repeated until
  an event occurs.
• Whenever this construct appears, the process
  first executes a task and then a test checks for
  a true or a false condition.
• The following figures shows the repeat-until-true
  and repeat-until-false.

11
Repeat-Until Example

• Reads the keyboard until a CR (carriage return)
  is detected.

12
Do-While

• Is comparable to the repeat-until except for one
  basic difference.
• The do-while construct checks the condition and
  then, if required, performs the process and
  repeats the check.
• There are two forms do-while-false and
  do-while-true.
