GT$¶
| Syntax | GT$ (type, string1$, string2$) |
| Location | Btool |
This function allows you to compare two strings using the comparison types supported by QDOS - it is therefore more flexible than direct comparison using operators (see Appendix 11). The function will always return 1 if string1$ is greater than string2$ and is therefore similar to:
PRINT string1$ > string2$
However, you can specify one of four comparison types, which will affect the outcome:
| TYPE | Effect |
|---|---|
| 0 | Compare the two strings character by character |
| 1 | Ignore the case of the letters |
| 2 | If there is no difference in the characters, compare the values of any embedded numbers. |
| 3 | Ignore the case of the letters and still if there is no difference in the characters, compare the values of any embedded numbers. |
The characters are compared by using the following order:
SPACE
!"#$%&'()\*+,-/:;<=>?@[\\]^\_£{\|}~© 01234567890
