variable name and array

[Timmins]

I am having difficulty writing the script to check the value of an element of an array (say ZArray) using a for/next loop. I have three variables called G1, G2, G3 that contain the element numbers that I want to check using a for/next loop, rather than 3 separate routines. I would appreciate any suggestions how to write this (that is G?):

for (x;x<4;x++){
if (ZArray[G?]==some value){
do this
}
}

Thanks again.

for (x=0; x<4; x++){
if (ZArray[x] == someValue){
//do this
}
}

Thanks for your help, sorry I wasn't clear on the difficulty. I would like to test three different variables, called G1, G2, G3 using a for/next loop, so that instead of writing:

if y==ZArray[G1] etc.
if y==ZArray[G2] etc.
if y==ZArray[G3] etc.

I would like to write something like

for (x=1;x<4;x++){
if (y==ZArray["G"+x]) {etc
}
}

Any suggestions are appreciated.

What values will G1, G2, and G3 have. For example, will they be holding a number or actual data?

[Timmins]

They will be holding numbers ?and data in the sense that their value will vary, ie G1 may = 3 or 5, etc. Thanks again.

for (x=1;x<4;x++){
if (y==ZArray[_root["G"+x]]) {etc
}
}
