STR$
—Return string representation of number
STR$(X)
This function returns the STRing representation of the nunneric value
of the argument X. When the STR$ value is converted to each varia
ble represented in the argument, any number displayed is preceded
and followed by a space except for negative numbers which are pre
ceded by a minus sign. The counterpart of the STR$ function is the
VAL function.
EXAMPLE
PRINT STR$(123.45)
123.45
PRINT STR$(-89.03)
-89.03
PRINT STR$(1E20)
1E + 20

TAB
—Moves cursor to tab position in present statement
TAB(X)
This function moves the cursor forward if possible to a relative posi
tion on the text screen given by the argument X, starting with the left
most position of the current line. The value of the argument can
range from 0 to 255. If the current print position is already beyond
position X, TAB places the cursor in the X position in the next line.
TAB functions exactly like SPC for disk and printer files (using
PRINT#).SeeSPC.
EXAMPLE:
10 PMNT"COMMODORE"TAB(25)"128"
COMMODORE 128
TAN
—Return tangent of argument
TAN(X)
This function returns the tangent of X, where X is an angle in radians.
EXAMPLE:
PRINT TAN(.78S398163)
