Deleting leading zeros: What is the best way to delete leading zeros in a variable V[account] ?
For example, instead of "0000000741" I want to have "741".
One possibility is to add the value 0:

// Delete leading zeros if not empty
if V[account]
  set V[account] "&V[account]" + 0
endif

This works well if there are no more than 15 digits in V[account]. For larger strings you may use the following coding:

// delete leading zeros
  label del_zero
  Set V[x] &V[account](1,1)
  if V[x=0]
    Set V[account] "&V[account](2,100) "
    goto del_zero
  endif
