Call a function: Difference between revisions

=={{header|langur}}==

User-defined and built-in functions can be called using parentheses.

Built-in functions can also be called using an "unbounded list," which ends at a line return, EOF, closing parenthesis, curly brace, or square bracket, or before a comma preceding a line return.

=== parentheses ===

<lang langur>.x()

# call user-defined function</lang>

<lang langur>write(.key, ": ", .value)

# call built-in with parentheses</lang>

=== unbounded lists ===

<lang langur>write .key, ": ", .value

# call built-in with unbounded list</lang>

<lang langur>write .key, ": ", .value

# call built-in with unbounded list</lang>

<lang langur>val .sum = foldfrom(

f(.sum, .i, .c) .sum + toNumber(.c, 36) x .weight[.i],

0,

pseries len .code,

split ZLS, .code,

)

# split and pseries both using unbounded lists, ending before comma preceding line return
