Mid-script Function Calls - Formance Documentation

Numscript

Requires flag: experimental-mid-script-function-call

Call functions like balance() directly in variable declarations, and use arithmetic expressions in the vars block.

Function calls in vars#

Numscript

vars {
  number $current = balance(@users:1234, USD/2)
}

send [USD/2 $current] (
  source = @users:1234
  destination = @savings:1234
)

Without this feature, balance() can only be used inline. With it, you can capture the result in a variable and reference it multiple times.

Arithmetic expressions#

Numscript

vars {
  number $fee = 100
  number $total = balance(@users:1234, USD/2)
}

send [USD/2 $total] (
  source = @users:1234
  destination = {
    $fee to @platform:fees
    remaining to @merchants:5678
  }
)

set_tx_meta("fee", $fee)
set_tx_meta("total", $total)
