This example will show how to define an user-defined procedure and the various way you can call it. You can call it by using directly its name, or by using the keywords PROC or CALL'. All the way are somewhat equivalent. ==== SOURCE CODE ==== CLS PROCEDURE hello PRINT “HEY!” END PROC PROC hello hello[] CALL hello ==== SOURCE FILE ==== * procedures_hello_03.bas ==== HOW TO COMPILE AND RUN ==== The instructions here refer to compiling the example from the command line.
