Miscellaneous Text Facilities : ModifyText

Modifying a text attribute is achieved through use of the EDTEXT command, which gives a simple case-sensitive, string exchange facility operating on the attribute in question.

The EDTEXT command takes the general forms:


EDT text_type numberstring_1 string_2
text_type	is the text attribute in question, which can be any DRAW text attribute, including the name attributes OSFN and BSFN. If text_type is not specified, BTEX is assumed.
number	is the order of occurrence of string_1 within the target string. If this is omitted then the first occurrence, is assumed, if a value of 0 is specified then all occurrences of string_1 are processed (for example, replaced by string_2).

Several modification instructions can be given in the same command line. The command

EDT text_type APP string

appends the given string to the specified text attribute.

The examples display different syntax options for the EDTEXT command.


Target string: ‘The dog, the cat and the rabbit were in the garden’
EDT ’the’ ’that’		(change first occurrence of ‘the’ to ‘that’)
gives:	’The dog, that cat and the rabbit were in the garden’
EDT ’the rabbit’ ’Dolores’
gives:	’The dog, the cat and Dolores were in the garden’
EDT 2 ’the’ ’that’		(change second occurrence of ‘the’ to ‘that’)
gives:	’The dog, the cat and that rabbit were in the garden’
EDT 0 ’the’ ’that’		(change all occurrences of ‘the’ to ‘that’)
gives:	’The dog, that cat and that rabbit were in that garden’
EDT ’dog’ ’horse’ ’at’ ’ow’ 3 ’the’ my’
gives:	’The horse, the cow and the rabbit were in my garden’
EDT ’fox’ ’fish’		(no change, ‘fox’ is not found)
EDT PLTX 3 ’we’ ’a’		(attribute PLTX can be altered, if found)
EDT OSFN ’A3’ ’A4’		(OSFN can be altered, if found)
EDT DATE ’1990’ ’1991’		(DATE can be altered, if found)

Note:

When modifying intelligent text the intelligent text code itself must be specified, not the ‘resultant’ text.
