Do next command or block repeatedly.

Syntax

try [count]
  command
 
try [count]

  command
  ...
  command
}

Parameters

count
  • Decimal number from 2 to 100, tells how many times next command or block will be retried.

Example

sleeps 200 ; Set sleeps = 200 ms
 
10      ; Set 'output state' = 100000000000.....
 
cycle:  ; Define Label
 
; All of these bocks give the same results:
 
; =================================
; Optimal block
try 2   ; Do next block for 2 times
{       ; Define start of block (by brace)
  lsl 4 ; Do 'shift left' for 4 times
  lsr 4 ; Do 'shift right' for 4 times
}       ; Define end of block (by brace)
 
; =================================
; This block have same effect
try 2   ; Do next block for 2 times
{
  try 4 ; Do next comand for 4 times
    lsl ; Do 'shift left'
  try 4 ; Do next comand for 4 times
    lsr ; Do 'shift right'
}
 
; =================================
; Cascading example
try 2   ; Do next block for 2 times
{
  try 2 ; Do next block for 2 times
  {
    lsl
    lsl
  }
  try 2 ; Do next block for 2 times
  {
    lsr 2
  }
}
 
; =================================
; Cascading without braces
try 2   ; Do next command for 2 times
  try 2 ; Do next command for 2 times
    lsl ; The command
try 2   ; Do next command for 2 times
  try 2 ; Do next command for 2 times
    lsr ; The command
try 4   ; Do next command for 4 times
  lsl    ; The command
try 4   ; Do next command for 4 times
  lsr    ; The command
