I usually use Repeat loop to do these things
Code: [Select]Goto M //Start of Subroutine section. We want it to be at the top of the program, as all subroutines are accessed via lables //This code is skipped due to the Goto M statementLbl A //Subroutine ADisp "This is a fun sub"Disp "Its over 9000"EndLbl MDisp "Main program foo'!" //This is where normal program execution startsFor(F,-1,0 //The tricky bit. The first time the for loop loops, F=-1 and the if statement is true. Goto AIf F //Once the sub is executed, it reaches an End which it THINKS is the same end that ends the For loopGoto A //since the loop is still looping, control jumps [i]back into the for loop[/i]End //F is now 0 and the condition is false. Exit for loop :)
Goto M //Start of Subroutine section.
