I found a way to achieve the effect of WHILE keyword

@gaurav294
just modify this file robot\running\steprunner.py, near line 33
edit this function to

    def run_steps(self, steps):
        errors = []

        cursor = 0  # the index to execute
        keywords = [ str(step).lower() for step in steps ]
        
        while cursor < len(steps):
            try:
                step = steps[cursor]
                if str(step).lower() == "reloop":
                    assert "exit for loop if" in keywords or "exit for loop" in keywords,\
                        "both for loop and exit condition are needed"
                    cursor = 0
                    continue
                cursor += 1
                self.run_step(step)
            except ExecutionPassed as exception:
                ......

Then the RELOOP "keyword" can jump to the first line immediately but it won't carry the next element of the range.

So we can use it like this

*** Test Cases ***
Example_Case
    ${j}    set variable  ${0}
    :for    ${n}    in range    ${1}
    \       ${j}    set variable  ${${j}+1}
    \       log many    ${j}
    \       exit for loop if      ${j}==${1000}
    \       reloop
    log many        done    ${j}

this means

j=0
while True:
    j=j+1
    print j
    if j==1000: break
print "done", j

but a bit ugly
any other good modifies?

This is interesting but not something that will be directly added to RF. Native WHILE loop support may be added after we got IF/ELSE and TRY/EXCEPT done.

Wondering if any progress has been made on implementing IF/ELSE and TRY/EXCEPT ?
tnx
