SYS is a system function that transfers program control to an inde-
pendent subsystem.
Format:
SYS(mem adr)
mem adr is the starting address at which execution of the subsystem is
to begin. The value must be in the range 0 <address <65535.
TAB
TAB moves the cursor right to the specified column position.
Format:
TAB(arg n)
TAB moves the cursor to the n+ I position, where n is the number
obtained by resolving arg n.
Example:
?"QUARK"; SPC( 10); "W"
tllUARK W
?"QUARK";TAB(10);"W"

cursor location, whereas TAB skips to the 10+ lth
position on the row
