I am trying to create a dynamic ksh script and I have an issue.
I have a script a.ksh and it has got the following lines (for example)
The dynamic file is getting created but look at the file content, its not the same instead the output of each statement execution. I want the same text that I mention in the code. Any help would be appreciated.

shell_builtins, case, for, foreach, function, if, repeat, select, switch, until, while - shell command interpreter built-in commands
The shell command interpreters csh(1), ksh(1), and sh(1) have special built-in commands. The commands case, for, foreach, function, if,
repeat, select, switch, until, and while are commands in the syntax recognized by the shells. They are described in the Commands section of
the manual pages of the respective shells. The remaining commands listed in the table below are built into the shells for reasons such as
efficiency or data sharing between command invocations. They are described on their respective manual pages.

Bourne Shell, sh, Special Commands
Input/output redirection is now permitted for these commands. File descriptor 1 is the default output location. When Job Control is
enabled, additional Special Commands are added to the shell's environment.
In addition to these built-in reserved command words, sh also uses:
: No effect; the command does nothing. A zero exit code is returned.
.filename Read and execute commands from filename and return. The search path specified by PATH is used to find the directory con-
taining filename.
C shell, csh
Built-in commands are executed within the C shell. If a built-in command occurs as any component of a pipeline except the last, it is exe-
cuted in a subshell. In addition to these built-in reserved command words, csh also uses:
: Null command. This command is interpreted, but performs no action.
Korn Shell, ksh, Special Commands
Input/Output redirection is permitted. Unless otherwise indicated, the output is written on file descriptor 1 and the exit status, when
there is no syntax error, is zero.
Commands that are preceded by one or two * (asterisks) are treated specially in the following ways:
1. Variable assignment lists preceding the command remain in effect when the command completes.
2. I/O redirections are processed after variable assignments.
3. Errors cause a script that contains them to abort.
4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a vari-
able assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not
performed.
In addition to these built-in reserved command words, ksh also uses:
* : [ arg ... ] The command only expands parameters.
* .file [ arg ..Read the complete file then execute the commands. The commands are executed in the current shell environment. The search
path specified by PATH is used to find the directory containing file. If any arguments arg are given, they become the posi-
tional parameters. Otherwise, the positional parameters are unchanged. The exit status is the exit status of the last com-
mand executed. the loop termination test.
