dScript commands

goto

goto is used to transfer program execution to another point in the program. The target of a

goto command is always a label.

Example:

goto label1

gosub

gosub is used to call subroutines. The address of the next instruction following the gosub is

stored on the stack, control is then transferred to the subroutine. A return command at the

end of the subroutine then transfers control back to the instruction following the gosub

command.

Example:

gosub IncA ; call the subroutine IncA

... ; return here

...

goto somewhere

IncA: A = A + 1 ; perform the task

return ; return to instruction following the gosub

return

return is used at the end of a subroutine. It pops the return address off the stack and transfers

control to that address.

if - single statement execution

The "if" command is used to make a decision on what to do next. The simplest form of the if

command to conditionally execute a single instruction.

if <condition> statement.

This most commonly would be a goto instruction.

if A > B goto BigA

however any single instruction may be executed.

This simple form of the if command does not require endif and cannot use else to provide an

alternative operation.
