Since version 0.9

Syntax:

[call] <proc_name> [(<argument1>, <argument2>, ...)]

The CALL command calls a procedure.

proc_name is the identifier of a previously defined procedure. The argument list is optional.

See PROC ... ENDPROC for more information and examples.

Since version 2.2, the CALL keyword as well as the parentheses can be omitted and thus procedures can be called as if they were commands. For example:

const LT_BLUE = 14

rem ** Clears the screen and sets color **
proc cls(color!)
  memset $0400, 1000, 32
  memset $d800, 1000, color!
endproc

rem ** Call the routine **
cls LT_BLUE
print "screen cleared"
