Comments

This script function replaces a character or string within a string.

Old and New are optional and not limited. If Old is not specified as a parameter, each individual empty space is replaced by the New character or string. If New is not specified as a parameter, Old is replaced by an individual empty space.

If Old is not included in the string, this function returns the string.

This script function can also be used to delete Old from the string. For this, New must be specified with two successive quotation marks (without empty spaces).

Example

The first example demonstrates how you replace the character "A" with character "B". The result "BBBBB" is output in the activation protocol.

:SET &RET# = STR_SUBSTITUTE ("AAAAA", "A", "B")
:
PRINT &RET#

The second example demonstrates how the string "AAAAA" is replaced by character "B". The result "B" is output in the activation protocol.

:SET &RET# = STR_SUBSTITUTE ("AAAAA", "AAAAA", "B")
:
PRINT &RET#

The third example demonstrates how the string "AA" is replaced with the string "BB". The result  "BBBBA" is output in the activation protocol.

:SET &STR1# = "AA"
:
SET &STR2# = "BB"
:
SET &RET# = STR_SUB ("AAAAA", &STR1#, &STR2#)
:
PRINT &RET#

The fourth example demonstrates how to delete the empty spaces from the string. The result "AE" is output in the activation protocol.

:SET &RET# = STR_SUB ("A E", " ", "")
:
PRINT  &RET#
