Caché ObjectScript CommandsQUIT and GOTOThe QUIT command within the block of code ends the WHILE loop and returns executionto the command following the closing curly brace, as shown in the following example:MainloopSET x=1WHILE x < 10{WRITE !,"looping "SET x=x+1WRITE " x=",xQUIT}WRITE " done"returns: looping x=2 doneA GOTO command within the block of code may direct execution to a tag outside the loop,terminating the loop. A GOTO command within the block of code may direct execution toa tag within the same block of code; this tag may be in a nested code block. A GOTO commandwithin the block of code may not direct execution to a tag within another code block.The following forms of GOTO are legal:mainloop ; Example of a GOTO to outside of the code blockWHILE 1=1 {WRITE !,"In an infinite WHILE loop"GOTO tagWRITE !,"This should not display"}WRITE !,"This should not display"tagWRITE !,"Went to tag and quit"QUITmainloop ; Example of a GOTO to within the code blockSET x=1WHILE x
