I try the way you told me but getting the following error

# ./robot.ksh
++ TRY=1
++ word1=
./robot.ksh: line 16: syntax error in conditional expression
./robot.ksh: line 16: syntax error near `-a'
./robot.ksh: line 16: `while [[ TRY -lt 4 -a "$word1" != "slot" ]]'
#

2. Please use code tags. It's no fun reading such scripts with no formatting. I edited your post - it now has code tags.
3. Please try it again with doube square brackets like:

Code:

while [[ $ERRORCODE -gt 0 -a $TRY -lt 4 ]]

4. Also to be sure maybe start using variables in this form:

Code:

${VAR}

5. Use set -x to debug your script
6. Use echo on your variables to debug your script

NAME

       let - shell built-in function to evaluate one or more arithmetic expressions

SYNOPSIS

   ksh
       let arg...

   ksh93
       let [expr...]

DESCRIPTION

   ksh
       Each arg is a separate arithmetic expression to be evaluated.

   ksh93
       let  evaluates  each expr in the current shell environment as an arithmetic expression using ANSI C syntax. Variables names are shell vari-
       ables and they are recursively evaluated as arithmetic expressions to get numerical values. let has been made obsolete by the ((...))  syn-
       tax of ksh93(1) which does not require quoting of the operators to pass them as command arguments.

EXIT STATUS

   ksh
       ksh returns the following exit values:

       0    The value of the last expression is non-zero.

       1    The value of the last expression is zero.

   ksh93
       ksh93 returns the following exit values:

       0     The last expr evaluates to a non-zero value.

       >0    The last expr evaluates to 0 or an error occurred.
