prepositions- In time you should be able to do the following with this program: - Question is this a correct use of a preposition?

Yes, it's the correct use of both prepositions. However, the phrase in time is not completely clear. I suggest you change it to Within a short time, . . .

To determine if "in time" is a correct use of a preposition, we need to understand the function of prepositions. Prepositions are words that show a relationship between a noun or pronoun and other words in a sentence. They often indicate location, direction, time, or manner.

In the phrase "in time," the preposition "in" indicates a relationship with the noun "time." It implies that something will happen within a certain timeframe or before a particular event takes place.

Therefore, the use of "in time" as a prepositional phrase is correct. However, it is worth mentioning that the phrase can be a bit ambiguous without additional context. To make it clearer, you can rephrase it as "Within a short time, you should be able to do the following with this program."
