PROCREAD statement
Syntax
PROCREAD variable{THEN statements [ELSE statements] | ELSE statements}
Description
Use the PROCREAD statement to assign the contents of the primary input buffer to a variable. Your BASIC program must be called by a procedure. If your program was not called from a procedure, the ELSE statements are executed; otherwise the THEN statements are executed.
If variable evaluates to the null value, the PROCREAD statement fails and the program terminates with a run-time error message.
