The following program prompts for the entry of a 2-letter state abbreviation and lists the clients within that state. If the program fails to return a list of clients, the programmer might insert the SUSPEND command just after the second CLEAR to halt the program so that trouble shooting commands could be issued at the Command window such as:?mState to determine the value in the variable mState, LIST FOR STATE_PROV = "CA", DISPLAY MEMORY, DISPLAY STATUS. Issue the command RESUME when ready to proceed with the remainder of the program:

CLEAR

SET TALK OFF

ACCEPT "Enter 2 letter State abbreviation: " TO mState

CLEAR

SUSPEND      // To be removed after troubleshooting

? CENTER( "Clients in " + UPPER( mState ) )

?

SCAN FOR State_Prov = UPPER( mState )
