I’m working with dBase III Dos based. Is there a way to insert an ESC Sequence command into dBase III. I’m trying to use a signature font and it use a sequence command which is “<ESC>(5Q<ESC>(s1p36.0v0s060T ”. The issue is whenever you hit the esc but
ton, it wants to exit or cancel. Help Please

Try using chr(27) or {27} in the string where you want an escape. =20
That's what I use in dBase IV. I don't know if III is the same, but it=20
might be.

dBase III+ will recognize the chr(27), which is exactly what needs to be
inserted into the string above:

? chr(27) + "(5Q" + chr(27) + "(s1p36.0v0s060T"

The curly bracket notation was introduced with dBase IV.

Many thanks Marilyn and David for you input.

My question for Marilyn is the font signature esc sequence is <ESC>(5Q<ESC>(s1p36.0v0s060T, however the command I insert in Dbase was ? chr(27) + "(5Q" + chr(27) + "(s1p36.0v0s060T". Do I need the ?, ", and + signs as well as all the spaces.

Thanks for your help guys.

The spaces are optional. The quotes and plus sign are not optional.
The ? can be a ? or a ??, but must be one of the two.

The ? is a dBase command which tells the computer to send the character
string which follows to the printer and send a carriage return/line feed
combination first. The ?? is a dBase command which tells the computer
to send the character string which follows to the printer and don't move
the current position.

The quotes are necessary because you are building a character string.
Without the quotes, dBase would assume the information was a memory
variable or a function or a number or something else and stop with an
error message, as it couldn't figure out what you were trying to do.

The plus sign helps you build the correct character string. You are
using a built-in function (chr()) to convert the number 27 to an escape
character, then appending the rest of the coded string.

Hope this helps.
