TGAL Procedures You can use the following procedures to modify TGAL code according to your

individualized needs. The procedures are presented in alphabetic order; each is

preceded by a brief explanation.

BANNER Procedure The BANNER procedure prints the banner string when TGAL runs interactively. The

banner can be up to 40 characters long. You should change this procedure whenever

you change any other procedure to help identify the version of TGAL you are running.

You should change the T9607B00 field to your logo or another distinctive word. In the

TGALUPS file, this procedure is:

PROC BANNER(S,L); !

STRING .s; ! 40-character banner string !

INT .L; ! length of banner !

BEGIN ! !

STRING .SP; points at end of string !

S ':=' "TGAL - T9607B00 - (01DEC84)"->@SP; ! tell who we are !

L := @SP'-'@S; ! tell them how long it is !

END; ! end of banner procedure !

banner. You do not supply additional information; for example:
