The CHANGE statement operates on a variable and replaces all occurrences of one string with another. It takes the form:
CHANGE expression1 TO expression2 IN variable
- expression1 may evaluate to any result and is the string of characters that will be replaced,
- expression2 may also evaluate to any result and is the string of characters that will replace expression1,
- variable may be any previously assigned variable in the program.
There is no requirement that strings be of the same length. The jBASE BASIC language also supports the CHANGE function for compatibility with older systems.
An example of use is as:
String1 = "Jim" String2 = "James" Variable = "Pick up the tab Jim" CHANGE String1 TO String2 IN Variable CHANGE "tab" TO "check" IN Variable
Go back to jBASE BASIC.
