The example below searches for spaces in the string assigned to the variable [name] and if found removes all characters that follow. The modified string is placed back into the [name] variable:

SetVar [name] "John Doe"

SearchStr " " "[Name]" [SpacePos]

If [SpacePos] > "0"

  StrLen "[Name]" [Len]

  StrDel "[Name]" [SpacePos] "[Len]-[SpacePos]" [name]

EndIf

SetVar [Sentence] "This is a multiple word phrase"

StrSearch " " "[Sentence]" "[SpacePos]"

While [SpacePos] > 0

  StrDel "[Sentence]" [SpacePos] 1 [Sentence] 

  SearchStr " " "[Sentence]" [SpacePos]

EndWhile

Purpose:

Convert the contents of a string to upper case. Numbers and punctuation within the string are not affected.

Category:

old chars

The characters to replace.

new chars

options

Enter "CaseSensitive" here to search using the exact characters entered. Leave this parameter blank to perform a case insensitive search (upper and lower case characters are treated the same).

Example:

The following example replaces each occurrence of the word "dog" in the source string with "cat":

StrReplace "My dog is a good dog." "dog" "cat" [Result] ""

You can also use this Action to remove a character by leaving the replacement characters parameter empty. For example:

StrReplace "My doggy is a good doggy." "gy" "" [Result] ""

Purpose:

Separate a string into multiple parts using a delimiter character.

Category:

Strings

Syntax:

StrParse "source string" "delimiter" "variable"

source string

The string containing the information to parse.

delimiter

The character (or characters) used to separate the elements of the string.

variable

The name of the variable array to store the parsed elements.

Each element in the string must be separated by the delimiter character (semicolon, comma, hyphen, etc.). StrParse will use the delimiter to divide the source string into individual elements which are placed into an array based on the array variable. The count variable will be set to the number of elements stored in the array.

Example:

The example below takes a list of names separates each one into individual names:

SetVar [List] "Peter,John,Olivia,Bruce,Dana"

StrParse "[List]" "," [Names]

.-> John

AlertBox "" "[Names(1)]" "" 

When executed, an array based on the [Names] variable will be created. Each element in the array will contain one name.
