# CMDLIN > [HTML Version](cmdlinsystemvariable.htm) This system variable is automatically set to contain the remainder of the command line used to start the current program. For example, if the program was started with: RUN FALALA do re mi Then A\$=CMDLIN would set A\$ to "DO RE MI" (always folded to upper case). xcall LSTLIN, A\$, on the other hand, would return "RUN FALALA do re mi," the complete command line with no folding.
