Did you read the answers to your other thread attentively? They mentioned the "step" parameter of the for command - you might try to adapt it to your problem?
And, you might want to read the man page of your shell to learn about the correct syntax of the (mandatory to your problem) while statement - as you used it, the shell will issue a "syntax error".

error::pass1
ERROR::PASS1(7stap) ERROR::PASS1(7stap)
NAME
error::pass1 - systemtap pass-1 errors
DESCRIPTION
Errors that occur during pass 1 (parsing) usually mean a basic syntax error of some sort occurred in the systemtap script. There are sev-
eral classes of problems possible:
plain syntax error
The systemtap script parser detects a large variety of errors, such as missing operands, bad punctuation. It tries to list what
kinds of tokens it was expecting to see, and will show the region of the source code with the problem. Please review the stap(1)
man page and/or the tutorial, to correct the script's syntax.
grammar ambiguities
There is at least one known ambiguity in the systemtap grammar. It relates to the optionality of ; (semicolon) separators between
statements, and the ++ and -- increment/decrement operators. If the parser indicates an error, consider adding some explicit ; sep-
arators between nearby statements and try again.
missing command line arguments
A systemtap script that uses the $N and @N constructs for substituting in command-line options may fail if not enough options were
given on the stap command line.
compatibility changes
Some versions of systemtap have changed the language incompatibly, for example by adding the try/catch keywords for exception han-
dling. In such cases, rerun systemtap with the --compatibility=VERSION option, substituting the last systemtap version where your
script was known to work. You may also check the release-history NEWS file for compatibility changes.
GATHERING MORE INFORMATION
Increasing the verbosity of pass-1 with an option such as --vp 1 can help pinpoint the problem.
