Desk Calculator Operations
You can perform several desk calculator operations using BASIC statements
without preceding statement numbers. These operations are executed
immediately after you press the EXECUTE key. Desk calculator operations
include:
• Assignment of values to variables (both character and numeric) without the
keyword LET
• PRINT (to display) and PRINT FLP (to print) statements
• MAT PRINT and MAT PRINT FLP statements
• DIM statements to dimension arrays and variables
• Character and numeric expressions
• MAT assignment statements
