CALL SCRN1 - Activates Screen 1.
CALL SCRN2 - Activates Screen 2.
CALL SCREEN2(color-code) - Replaces CALL LINK("SCREEN",P). color-code (1 to 16) sets the screen color.
CALL COLOR2(character-set, foreground-color, background-color [,...]) - Replaces CALL LINK("COLOR",P). Used to specify foreground/background colors for characters in a set for screen 2. 
CALL CHAR2(character-code, pattern-identifier [....]) - Replaces CALL LINK("CHAR",P). Defines character pattern(s) of screen 2. character-code is 0-255. pattern-identifier is a 0-64 character hexadecimal string.
CALL CHPAT2(character-code, string-variable [,...]) - Equivalent of CALL CHARPAT in XB. Returns the pattern identifier in string-variable of screen 2. Character-code must be 0 to 255. Up to 8 patterns can be read.
CALL CHSET2 - Restores default characters 32-127 and copies them to 160-255 in inverse video.
CALL CHSETL - Variation of CHSET2 using larger capital letters.
CALL CHSETD - Variation of CHSET2 using true lowercase characters with descenders.
CALL WINDOW[row1, col1, row2, col2] - Sets boundaries for scrolling and DISPLY. Without parameters, sets the full screen (1, 1, 24, 32).
CALL SCRLUP - Scrolls characters in the defined window up. 
CALL SCRLDN - Scrolls characters in the window down.
CALL SCRLRT - Scrolls characters in the window right.
CALL SCRLLF - Scrolls characters in the window left.
CALL CRAWL(string) - Performs a text crawl.
CALL SCPXRT(ascii code, length, #pixels [,...]) - Shifts character definitions right by the specified #pixels. Up to 5 sequences can be modified per call. (Screen 2 only)
CALL SCPXLF(ascii code, length, #pixels [,...]) - Shifts character definitions left by #pixels. (Screen 2 only)
CALL SCPXUP(ascii code, length, #pixels [,...]) - Shifts character definitions up by #pixels. (Screen 2 only)
CALL SCPXDN(ascii code, length, #pixels [,...]) - Shifts character definitions down by #pixels. (Screen 2 only)
CALL DISPLY(row, col, string [,direction, repeat]) - Prints a string on the screen starting at row and col (column 1 is the first column). direction and repeat are optional.
CALL HILITE(row, column, length) - Toggles text to inverse video or back. row is 1–24, column is 1–32, length is 1–256. (Screen 2 only)
CALL VREAD(memory address, # bytes, string [,...]) - Reads # bytes from VDP RAM into up to 5 string variables.
CALL VWRITE(memory address, string [,...]) - Writes up to 8 strings to VDP RAM starting at memory address. For displaying characters in memory location 0 to 767 the value needs to be shifted by 96 modulo 256 from the ASCII value. 
CALL CWRITE(compressed string [,...]) - Writes up to 16 compressed strings to VDP RAM. 
CALL PLAY(vdp address)  - Starts playing the sound list located at vdp address in VDP RAM. Using 0 stops any currently playing sounds.
CALL ST2VDP(1 or 2) - Copies an assembled sound table from CPU RAM into VDP RAM buffer 1 (at address 2432) or buffer 2 (at address 6176).
CALL EARLYC(#Sprite[,...]) - Sets the sprite(s) early clock, meaning they are shifted 32 pixel left to appear in part on the left side of the screen.
CALL FREEZE - Turns off automatic sprite motion for all sprites.
CALL THAW - Turns on automatic sprite motion for all sprites.
CALL DELAY(milliseconds) - Pauses execution for a specified duration.
CALL SYNC(N) - Replaces CALL LOAD(-1,N). Sets the V-sync cycle interval where N/60 is the desired loop time.
CALL SYNC - Wait until the counter set with CALL SYNC(N) was counted down to zero.
CALL IRND(limit, variable [,...]) - Returns an integer random number from 0 to limit-1. Up to 8 random numbers can be generated.
CALL CAT - Catalogs a disk drive.
CALL RUN(A$) - Runs an XB256 program using the filename specified in the string variable A$.
CALL RUNL1(A$) - Runs an XB256 program using filename A$, starting execution at line 1 and preserving variables by bypassing the prescan.
CALL SAVEIV(A$) - Saves the currently loaded program to disk in IV254 format, using the filename specified in A$.
CALL SPEED(S,X,Y) - Returns the speed of Sprite S. This is a TiCodEd function and the sprite number is without hash-sign.
