convert printer code to string of chr()

[Richard D. Williams]

I need to change print codes for font size within a string.

I can do it for bold on, bold off, underline on, underline off;

bold on:
declare hp_bold_on;hp_bold_on= 
chr("27"){chr("40"){chr("115"){chr("51"){chr("66"){""

bold off:
declare hp_bold_off;hp_bold_off= 
chr("27"){chr("40"){chr("115"){chr("48"){chr("66"){""

underline on:
declare 
hp_ul_on;hp_ul_on=chr("27"){chr("38"){chr("100"){chr("51"){chr("68"){""

underline off:
declare hp_ul_off;hp_ul_off=chr("27"){chr("38"){chr("100"){chr("64"){""


but I am having a difficult time with these codes;

$1b ( s 10 H

$1b ( s 12 H

$1b ( s 16.6 H

I guess part of my problem is the parenthesis.
Can any one help me out?
