GT$ (type, string1$, string2$) |

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
