| SUB...END SUB Statement Programming Examples |
|
| SUB_EX.BAS is a program file in the subdirectory ADVR_EX that illustrates |
| the SUB...END SUB statement. To look at the program in the View window and, |
| optionally, to run it, load the program using the File menu's Open Program |
| command. |
| |
| The main program calls a subprogram which searches for a given string in |
| each line of input from a file. When the subprogram finds the string in a |
| line, it prints the line, along with the number of the line. Notice that |
| the value of a line number counter is saved between calls because the |
| STATIC keyword is used on the SUB statement. |
| |
| Below is sample output from the program: |
| |
| Pattern to search for? SUB |
| Line # 9 : SUB Linesearch(Test$,P$) STATIC |
| Line # 13 : END SUB |
